data sheet 2 rev. 1.0 2017-08-09 hs can transceiver high speed can transceiver overview description the TLE9251V is the latest infineon high-speed can transceiver generation , used inside hs can networks for automotive and also for industrial a pplications. it is designed to fulf ill the requirements of iso 11898-2 (2016) physical layer specification and respecti vely also the sae standards j1939 and j2284. the TLE9251V is available in a pg-dso -8 package and in a small, leadless pg-tson-8 package. both packages are rohs compliant and halogen fr ee. additionally the pg-tson-8 pa ckage supports the solder joint requirements for automated optical inspection (aoi). as an interface between the physical bus layer and the hs can protocol co ntroller, the TLE9251V protects the microcontroller against interferences generated inside the network. a very high esd robustness and the perfect rf immunity allows the use in automotive application without addi ng additional protection devices, like suppressor diodes for example. while the transceiver TLE9251V is not s upplied the bus is switched off and illustrate an ideal passive behavior with the lowest possible load to all other subscribers of the hs can network. based on the high symmetry of the ca nh and canl output signals, the tl e9251v provides a very low level of electromagnetic emission (e me) within a wide frequency range. the TLE9251V fulfills even stringent emc test limits without additional ex ternal circuit, like a common mode choke for example. the perfect transmitter symmetry comb ined with the optimized delay symm etry of the receiver enables the TLE9251V to support can fd data frames. depending on the size of the network and the along coming parasitic effects the device su pports bit rates up to 5 mbit/s. dedicated low-power modes, like stand-by mode prov ide very low quiescent curr ents while the device is powered up. in stand-by mode the typical quiescent current on v io is below 10 a while the device can still be waked up by a bus signal on the hs can bus. fail-safe features like overtemperat ure protection, output current limita tion or the txd time-out feature protect the TLE9251V and the external circuitry from ir reparable damage. type package marking TLE9251Vle pg-tson-8 9251v TLE9251Vsj pg-dso-8 9251v data sheet 3 rev. 1.0 2017-08-09 hs can transceiver high

transceiver high speed can transceiver high-speed can functional description 4 high-speed can functional description hs can is a serial bus system that connects microcon trollers, sensors and actuators for real-time control applications. the use of the controller area network (abbreviated can) within road vehicles is described by the international standard iso 11898. according to the 7-layer osi reference model the physical layer of a hs can bus system specifies the data transmission from one can node to all other available can nodes within the network. the physical layer specification of a can bus system includes all electrical specifications of a can network. the can transceiver is part of the physical layer specificatio n. several different physical layer standards of can networks have been developed in recent years. the tle 9251v is a high-speed can transceiver with a dedicated bus wa ke-up function as defined in th e latest iso 11898-2 hs can standard. 4.1

high speed can transceiver high-speed can functional description the TLE9251V is a high-speed can tran sceiver, operating as an interface between the can controller and the physical bus medium. a hs can network is a two wire, differential network which allows data transmission rates up to 5 mbit/s. the characteristic for a hs ca n network are the two signal states on the can bus: ?dominant? and ?recessive? (see figure 3 ). the canh and canl pins are the interface to the can bu s and both pins operate as an input and output. the rxd and txd pins are the interface to the microcontroller. the pin txd is the serial data input from the can controller, the rxd pin is the serial data output to the can cont roller. as shown in figure 1 , the hs can transceiver TLE9251V includes a receiver and a transmitter unit, allowing the transceiver to send data to the bus medium and monitor the data fr om the bus medium at the same time. the hs can transceiver TLE9251V converts the serial data stream which is available on the transmit data input txd, into a differential output signal on the can bus, provided by the canh and canl pins. the receiver stage of the TLE9251V monitors the data on the can bus and conv erts them to a serial, single-ended signal on the rxd output pin. a logical ?low? signal on the txd pin creates a ?dominant? signal on th e can bus, followed by a logical ?low? signal on the rxd pin (see figure 3 ). the feature, broadcasting da ta to the can bus and listenin g to the data traffic on the can bus simultaneously is essential to support the bit-to-bit arbitration within can networks. the voltage levels for hs can transc eivers are defined in iso 11898-2. whether a data bit is ?dominant? or ?recessive? depends on the voltage differ ence between the canh and canl pins: v diff = v canh - v canl . to transmit a ?dominant? signal to the can b us the amplitude of the differential signal v diff is higher than or equal to 1.5 v. to receive a ?rec essive? signal from the can bus the amplitude of the differential v diff is lower than or equal to 0.5 v. ?partially-supplied? high-speed can networks are th ose where the can bus nodes of one common network have different power supply conditions. some nodes are connected to the common power supply, while other nodes are disconnected from the powe r supply and in power-down state. regardless of whether the can bus subscriber is supplied or not, each subscriber co nnected to the common bus media must not interfere with the communication. the TLE9251V is designed to su pport ?partially-s upplied? networks. in power-down state, the receiver input resistors are switched of f and the transceiver input has a high resistance. for permanently supplied ec u's, the hs can transceiver TLE9251V pr ovides a stand-by mode. in stand-by mode, the power consumption of the TLE9251V is optimize d to a minimum, while the device is still able to recognize wake-up patterns on the can bus and signal the wake-up event to the external microcontroller. the voltage level on the digital input txd and the digita l output rxd is determined by the power supply level at the v io pin. depending on the voltage level at the v io pin, the signal levels on the logic pins (stb, txd and rxd) are compatible with microcontrollers having a 5 v or 3.3 v i/o supply. usually the digital power supply v io of the transceiver is connected to the i/ o power supply of the microcontroller (see figure 18 ). data sheet 8 rev. 1.0 2017-08-09 hs can transceiver high speed can transceiver modes of operation 5 modes of operation the TLE9251V supports three diff erent modes of operation (see figure 4 and table 2 ): ? normal-operating mode ?stand-by mode ?forced-receive-only mode mode changes are either triggered by the mode selectio n input pin stb or by an undervoltage event on the transmitter supply v cc . wake-up events on the hs can bus are indicated on the rxd output pin in stand-by mode, but no mode change is triggered by a wake-up event. an undervoltage event on the digital supply v io powers down the TLE9251V. figure 4 mode state diagram table 2 modes of operation mode stb v io v cc bus bias transmitter normal-mode receiver low-power receiver normal-operating ?low?

signal on the txd pin might have its root cause in a locked- up microcontroller or in a short circuit on the printed circuit board, for example. in normal-operating mode, a logical ?low? signal on the txd pin for the time t > t txd enables the txd time-out feature and the TLE9251V disa bles the transmitter (see figure 13 ). the receiver is still active and the data on the bus continues to be monitored by the rxd output pin. figure 13 txd time-out function figure 13 illustrates how the transmitter is deactivated and activa ted again. a permanent ?low? signal on the txd input pin activates the txd time-out function and de activates the transmitter. to release the transmitter after a txd time-out event, the TLE9251V requires a sign al change on the txd input pin from logical ?low?
