Description The TLE7259-2GU is a follow-up product of the TLE7259-2GE. It provides the same functions and it is pin compatible to the TLE7259-2GE. The TLE7259-2GU is designed for in-vehicle networks using data transmission rates from 2.4 kBaud to 10.4 kBaud according to the SAE J2602 standard. The TLE7259-2GU functions as a bus driver between the protocol controller and the physical bus inside the LIN network. Compliant to all LIN standards and with a wide operational supply range the TLE7259-2GU can be used in all automotive applications. Different operation modes and the INH output allow the TLE7259-2GU to control external components, like voltage regulators. In Sleep-mode the TLE7259-2GU draws less than 8 A of quiescent current, while still being able to wake up off of LIN bus traffic and a local Wake-Up input. The very low leakage current on the BUS pin makes the TLE7259-2GU especially suitable for partially supplied networks and supports the low quiescent current requirements of the LIN network. Based on the Infineon Smart Power Technology SPT(R), the TLE7259-2GU provides excellent ESD Robustness together with a very high electromagnetic immunity (EMI). The TLE7259-2GU reaches a very low level of electromagnetic emission (EME) within a broad frequency range and independent form the battery voltage. The Infineon Smart Power Technology SPT(R) allows bipolar and CMOS control circuitry in accordance with DMOS power devices existing on the same monolithic circuit. The TLE7259-2GU and the Infineon SPT(R) technology are AEC qualified and tailored to withstand the harsh condition of the Automotive Environment.

Functional Description
The LIN Bus is a single wire, bi-directional bus, used for in-vehicle networks. The LIN Transceiver TLE7259-2GU is the interface between the microcontroller and the physical LIN Bus (see Figure 15 and Figure 16). The logical values of the microcontroller are driven to the LIN bus via the TxD input of the TLE7259-2GU. The transmit data stream on the TxD input is converted to a LIN bus signal with optimized slew rate to minimize the EME level off the LIN network. The RxD output reads back the information from the LIN bus to the microcontroller. The receiver has an integrated filter network to suppress noise on the LIN Bus and to increase the EMI (Electro Magnetic Immunity) level of the transceiver. Two logical states are possible on the LIN bus according to the LIN Specification 2.1 (see Figure 3): In dominant state, the voltage on the LIN bus is set to the GND level. In recessive state, the voltage on the LIN bus is set to the supply voltage VS. By setting the TxD input of the TLE7259-2GU to "Low" the transceiver generates a dominant level on the BUS interface pin. The RxD output reads back the signal on the LIN bus and indicates a dominant LIN bus signal with a logical "Low" to the microcontroller. Setting the TXD pin to "High" the transceiver TLE7259-2GU sets the LIN interface pin BUS, to the recessive level, at the same time the recessive level on the LIN bus is indicated by a logical "High" on the RxD output. Every LIN network consists of a master node and one or more slave nodes. To configure the TLE7259-2GU for master node applications, a resistor of 1 k and a reverse diode must be connected between the LIN bus and the power supply VS or the INH pin of the TLE7259-2GU (see Figure 15 and Figure 16).

TLE7259-2GU
Functional Description The TLE7259-2GU has 3 major operation modes: * * * Stand-By mode Normal Operation mode Sleep mode
The Normal Operation mode contains 2 sub-operation modes, which differentiate by the slew rate control of the LIN Bus signal (see Figure 4). Sub-operation modes with different slew rates on the BUS pin: * * Low Slope mode, for data transmission rates up to 10.4 kBaud Flash mode, for programming of the external microcontroller
The operation mode of the TLE7259-2GU is selected by the EN pin. (see Figure 4). Table 1 Mode Sleep Stand-By Operating modes EN Low Low INH TxD RxD High1) Low High 1) LIN Bus Comments Termination High Impedance 30 k (typical) No wake-up request detected RxD "Low" after local Wake-Up (pin WK) or bus Wake-Up (pin BUS) RxD "High" after Power-Up TxD strong pull down after local Wake-Up (WK pin)2) TxD weak pull down after bus Wake-Up (pin BUS) or Power-Up2) RxD reflects the signal on the BUS TxD driven by the microcontroller

1) A pull-up resistor to the external microcontroller supply is required. 2) The TxD input needs an external termination to indicate a "High" or a "Low" signal. The external termination could be a pull-up resistor or an active microcontroller output.
4.2
Normal Operation Mode
The TLE7259-2GU enters the Normal Operation mode after the microcontroller sets EN to "High" (see Figure 4). In Normal Operation mode the LIN bus receiver and the LIN bus transmitter are active. Data from the microcontroller is transmitted to the LIN bus via the TxD pin, the receiver detects the data stream on the LIN bus and forwards it to the RxD output pin. In Normal Operation mode, the INH pin is "High" (set to VS) and the bus termination is set to 30 k. The Low Slope mode and the Flash mode are Normal Operation modes and in these sub-modes the behavior of the INH pin and the bus termination is the same. Per default the TLE7259-2GU always enters into Low Slope mode, either from Sleep mode or from Stand-By mode. The Flash mode can only be entered from Low Slope mode. In order to avoid any bus disturbance during a mode change, the output stage of the TLE7259-2GU is disabled and set to recessive state during the mode change procedure. To release the TLE7259-2GU for data communication on the LIN bus, the TxD pin need to be set to "High" for the time tto,rec.

Functional Description
4.2.1
Low Slope Mode
In Low Slope mode data transmission rates up to 10.4 kBauds are possible. Setting the EN pin to "High" starts the transition to Low Slope mode. (see Figure 5). The mode change to Low Slope mode is defined by the time tMODE. The time tMODE specifies the delay time between the threshold, where the EN pin detects a "High" input signal, and the actual mode change of TLE7259-2GU into Low Slope mode. Entering in Normal Operation mode, the TLE7259-2GU always enters per default into Low Slope mode. The signal on the TxD pin is not relevant for entering into Low Slope mode. Finally to release the data communication it is required to set the TxD pin to "High" for the time tto,rec.

Flash Mode
In Flash mode it is possible to transmit and receive LIN messages on the LIN bus. The slew rate control mechanism of the LIN bus signal is disabled. This allows higher data transmission rates, disregarding the EMC limitations of the LIN network. The Flash mode is intended to be used during the ECU production for programming the microcontroller via the LIN bus interface. The TLE7259-2GU can be set to Flash mode only from Low Slope mode (see Figure 4). Flash mode is entered by setting the EN pin to "Low" for the time tfl1 and generating a falling and a rising edge at the TxD pin with the timing tfl2, tfl3 and tfl4 (see Figure 6). Leaving the Flash mode by the same sequence, sets the TLE7259-2GU back to Low Slope mode. Finally to release the data transmission it is required to set the TxD pin to "High" for the time tto,rec. Additionally the TLE7259-2GU can leave the Flash mode as well by switching only the EN pin to "Low". By applying this "Low" signal to the EN pin the TLE7259-2GU is put into Sleep mode.

Stand-By Mode
The Stand-By mode is entered automatically after: A Power-Up event on the supply VS. A bus Wake-Up event on pin BUS. A local Wake-Up event on the pin WK. A power on reset caused by power supply VS In Stand-By mode the Wake-Up sources are monitored by the TxD and RxD pins.
In Stand-By mode no communication on the LIN Bus is possible. The output stage is disabled and the LIN Bus termination remains activated. The RxD and the TxD pin are used to indicate the Wake-Up source or a Power-Up event. The RxD pin remains "Low"after a local Wake-Up event on the pin WK and a bus Wake-Up event on the LIN bus. A Power-Up event is indicated by a logical "High" on the RxD pin. The signal on the TxD pin indicates the Wake-Up source, a weak pull-down signals a bus Wake-Up event on the LIN bus and a strong pull-down signals a local Wake-Up event caused by the WK pin (see Table 1 and Table 2). In order to detect a Wake-Up event via the TxD pin, the external microcontroller output needs to provide a logical "High" signal. The Wake-Up flags indicating the Wake-Up source on the pins TxD and RxD are reset by changing the operation mode to Normal Operation mode. The signal on the EN pin remains "Low" due to an internal pull-down resistor. Setting the EN pin to "High", by the microcontroller returns the TLE7259-2GU to Normal Operation mode. In Stand-By mode the INH output is switching to VS. The INH output can be used to control external device like a voltage regulator.

1) To indicate the Wake-Up sources via the RxD pin a pull-up resistor to the external microcontroller supply is required. 2) The TxD input needs an external termination to indicate a "High" or a "Low" signal. The external termination could be a pull-up resistor or an active microcontroller output. 3) A local Wake-Up event is considered after a low signal on the pin WK (see Chapter 4.7). 4) A bus Wake-Up event is considered after a low to high transition on the LIN bus (see Chapter 4.6)

Sleep Mode
In order to reduce the current consumption the TLE7259-2GU offers a Sleep mode. In Sleep mode the quiescent current on VS and the leakage current on the pin BUS are cut back to a minimum. To switch the TLE7259-2GU from Normal Operation mode to Sleep mode, the EN pin has to be set to "Low". Conversely a logical "High" on the EN pin sets the device directly back to Normal Operation mode (see Figure 4). While the TLE7259-2GU is in Sleep mode the following functions are available: * The output stage is disabled and the internal bus terminations are switched off (High Impedance on the pin BUS). The internal current source on the bus pin ensures that the levels on the pin BUS remains recessive and protects the LIN network against accidental bus Wake-Up events. The receiver stage is turned off. RxD output pin is "High" if a pull-up resistor is connected to the external micro controller supply. The TxD pin is disabled. The logical state on the TxD pin is "Low", due to the internal pull-down resistor. The INH output is switched off and floating. The bus wake-up comparator is active and turns the TLE7259-2GU to Stand-By mode in case of a bus WakeUp event. The WK pin is active and turns the TLE7259-2GU to Stand-By mode in case of a local Wake-Up. The EN pin remains active, switching the EN pin to "High" changes the operation mode to Normal Slope mode.

Wake-Up Events
A Wake-Up event changes the operation mode of the TLE7259-2GU from Sleep mode to Stand-By mode. There are 3 different ways to wake-up the TLE7259-2GU from Sleep mode. * * * Bus Wake-Up via a dominant signal on the pin BUS. Local Wake-Up via a minimum dominant time (tWK) on the WK pin. Mode change from Sleep mode to Normal Operation mode, by setting the EN pin to logical "High".

TLE7259-2GU
Functional Description The bus Wake-Up event, often called remote Wake-Up, changes the operation mode from Sleep mode to StandBy mode. A falling edge on the LIN bus, followed by a dominant bus signal t > tWK,bus results in a bus Wake-Up event. The mode change to Stand-By mode becomes active with the following rising edge on the LIN bus. The TLE7259-2GU remains in Sleep mode until it detects a change from dominant to recessive on the LIN bus (see Figure 7). In Stand-By mode the TxD pin indicates the source of the Wake-Up event. A weak pull-down on the pin TxD indicates a bus Wake-Up event (see Figure 4). The RxD pin signals if a Wake-Up event occurred or the powerup event. A "Low" signal on the RxD pin reports a local or bus Wake-Up event, a logical "High" signal on RxD indicates a power-up event.

Figure 8 Local Wake-Up behavior
Beside the remote Wake-Up, a Wake-Up of the TLE7259-2GU via the WK pin is possible. This type of wake-up event is called "Local Wake Up". A falling edge on the WK pin followed by a "Low"signal for t > tWK results in a local Wake-Up (see Figure 8) and changes the operation mode to Stand-By mode. In Stand-By mode the TxD pin indicates the source of the Wake-Up event. A strong pull-down on the pin TxD indicates a bus Wake-Up event (see Figure 4). The RxD pin signals if a Wake-Up event or the Power-Up event occurred. A "Low" signal on the RxD pin reports a local or bus Wake-Up event, a logical "High"signal on RxD indicates a Power-Up event.

Mode Transition via EN pin
It is also possible to change from Sleep mode to Normal Operation mode by setting the EN pin to logical "High".This feature is useful if the external microcontroller is continuously powered and not connected to the INH pin. The EN pin has an integrated pull-down resistor to ensure the device remains in Sleep or Stand-By mode even if the voltage on the EN pin is floating. The EN pin has an integrated hysteresis (see Figure 9). A transition from logical "High"to logical "Low" on the EN pin changes the operation mode from Normal Operation mode to Sleep mode. If the TLE7259-2GU is already in Sleep mode, changing the EN from "Low"to "High" results into a mode change from Sleep mode to Normal Operation mode. If the device is in Stand-By mode a change from "Low"to "High" on the EN pin changes the mode to Normal Operation mode (see Figure 4).

Functional Description
4.9
TxD Time Out function
If the TxD signal is dominant for a time t > ttimeout the TxD time-out function deactivates the transmission of the LIN signal to the bus and disables the output stage. This is realized to prevent the bus from being blocked by a permanent "Low" signal on the TxD pin, caused by an error on the external microcontroller (see Figure 10). The transmission is released again, after a rising edge at the pin TxD has been detected.

Over Temperature protection
The TLE7259-2GU has an integrated over temperature sensor to protect the device against thermal overstress on the output stage. In case of an over temperature event, the temperature sensor will disable the output stage (see Figure 1). An over temperature event will not cause any mode change nor will it be signaled by either the RxD pin or the TxD pin. When the junction temperature falls below the thermal shut down level TJ < TjSD, the output stage is re-enabled and data communication can start again on the LIN bus. A 10C hysteresis avoids toggling during the temperature shut down.
4.11
3.3 V and 5 V Logic Capability
The TLE7259-2GU can be used for 3.3 V and 5 V microcontrollers. The inputs and the outputs are capable to operate with both voltage levels. The RxD output must have an external pull-up resistor to the microcontroller supply to define the output voltage level.
4.12
BUS Short to GND Feature
The TLE7259-2GU has a feature implemented to protect the battery from running out of charge in case the LIN bus is shorted to GND. In this failure case a normal master termination, a 1 k resistor and diode between the LIN bus and the power supply VS, would cause a constantly drawn current even in Sleep mode. The resulting resistance of this short to GND is in the range of1 k. To avoid this current during a generator off state, like in a parked car, the TLE72592GU has a bus short to GND feature implemented, which is activated in Sleep mode. Data Sheet 15 Rev. 1.1, 2008-07-14
TLE7259-2GU
Functional Description This feature is only applicable, if the master termination of the LIN bus is connected to the INH pin instead of being connected to the power supply VS (see Figure 15 and Figure 16). Internally, the 30 k path is also switched off from the power supply VS (see Figure 1). A separate Master Termination Switch is implemented at pin BUS, to avoid a voltage drop on the recessive level of LIN bus, in case of a dominant level or a short to ground on at the LIN bus.
4.13
LIN Specifications 1.2, 1.3, 2.0 and 2.1
The device fulfills the Physical Layer Specification of LIN 1.2, 1.3, 2.0 and 2.1. The differences between LIN specification 1.2 and 1.3 is mainly the physical layer specification. The reason was to improve the compatibility between the nodes. The LIN specification 2.0 is a super set of the 1.3 version. The 2.0 version offers new features. However, it is possible to use the LIN 1.3 slave node in a 2.0 node cluster, as long as the new features are not used. Vice versa it is possible to use a LIN 2.0 node in the 1.3 cluster without using the new features. In terms of the physical layer the LIN 2.1 Specification doesn't include any changes and is fully compliant to the LIN Specification 2.0. LIN 2.1 is the latest version of the LIN specification, released in December 2006.
4.14
SAE J2602-2
The TLE7259-2GU is EME (Electro - Magnetic - Emission) optimized for the requirements of the US automotive market. The timings of the TLE7259-2GU are compliant to the SAE J2602-2 standard.

Pin Compatibility to other LIN Transceivers
The LIN Transceiver TLE7259-2GU is pin and function compatible to the Single LIN Transceivers like the TLE7259G, the TLE7259-2GE and other single LIN Transceivers on the market. The TLE7259-2GU has no VIO supply pin. Therefore the TLE7259-2GU needs a pull-up resistor to the external microcontroller supply. The TLE7259-2GU can also be used on a PCB design for the Twin LIN TLE7269G. Since the TLE7269G doesn't need a pull-up resistor on the RxD pin, a pull-up resistor to the external microcontroller needs to be added to get the same functionality.

7.3
Master Termination
To achieve the required timings for the dominant to recessive transition of the bus signal an additional external termination resistor of 1 k is mandatory. It is recommended to place this resistor at the master node. To avoid reverse currents from the bus line into the battery supply line it is recommended to place a diode in series with the external pull-up. For small systems (low bus capacitance) the EMC performance of the system is supported by an additional capacitor of at least 1 nF at the master node (see Figure 15 and Figure 16).The values for the Master Termination resistor and the bus capacitances influence the performance of the LIN network. They depend on the number of nodes inside the LIN network and on the parasitic cable capacitance of the LIN bus wiring.
7.4
External Capacitors
A capacitor of 10 F at the supply voltage input VS buffers the input voltage. In combination with the required reverse polarity diode this prevents the device from a detecting power down conditions in case of negative transients on the supply line (see Figure 15 and Figure 16). The 100 nF capacitor close to the VS pin of the TLE7259-2GU is required to get the best EMC performance.
