TLE 6251 G
Description The CAN-transceiver TLE 6251 G is a monolithic integrated circuit in a P-DSO-14-13 package for high speed differential mode data transmission (up to 1 Mbaud) and reception in automotive and industrial applications. It works as an interface between the CAN protocol controller and the physical bus lines compatible to ISO/DIS 11898. As a successor to the first generation of HS CAN, the TLE 6251 G is designed to provide an excellent passive behavior when the transceiver is switched off (mixed networks, clamp15/30 applications). The current consumption can be reduced, due to the low power modes.. This supports networks with partially powered down nodes. The TLE 6251 G offers two low power modes as well as a receive-only mode to support software diagnosis functions. A wake-up from the low power mode is possible via a message on the bus or via the bi-level sensitive wake input. An external voltage supply IC can be controlled by the inhibit output. So, the C can be powered down and the TLE 6251 G still reacts to wake-up activities on the CAN bus or local wake input. A diagnosis output allows mode dependent enhanced diagnosis of bus failures and wake-up source. A VBAT fail flag reports an power-on condition at the battery supply input. The TLE 6251 G is designed to withstand the severe conditions of automotive applications and to support 12 V and 24 V applications. The IC is based on the Smart Power Technology SPT(R) which allows bipolar and CMOS control circuitry in accordance with DMOS power devices existing on the same monolithic circuit.

TLE 6251 G
Application Information As a successor to the first generation of HS CAN, the TLE 6251 G is designed to provide an excellent passive behavior when the transceiver is switched off (mixed networks, terminal 15/30 applications). The current consumption can be reduced, due to the low power modes. This supports networks with partially powered down nodes. A wake-up from the low power modes is possible via a message on the bus or via the bi-level sensitive wake input WK. An external voltage supply IC can be controlled by the inhibit output INH. So, the C can be powered down and the TLE 6251 G still reacts to wake-up activities on the CAN bus or local wake input activities. A diagnosis output pin NERR, allows mode dependent enhanced diagnosis of bus failures and wake-up source. A VBAT fail flag reports a power-on condition at the battery supply input. The VBAT fail flag will be resetted after the first transition into normal mode. The TLE 6251 G has four operation modes, the normal, the receive only, the standby mode and the sleep mode. These modes can be controlled with the two control pins EN and NSTB pin (see Figure 6, Table 2). Both, EN and NSTB, have an implemented pull-down, so if there is no signal applied to EN and NSTB, the transceiver automatically changes to the standby mode. Normal Mode To transfer the TLE 6251 G into the normal mode, NSTB and EN have to be switched to HIGH level. This mode is designed for the normal data transmission/reception within the HS-CAN network. Transmission The signal from the C is applied to the TxD input of the TLE 6251 G. Now the bus driver switches the CANH/L output stages to transfer this input signal to the CAN bus lines. TxD Time-out Feature If the TxD signal is dominant for a time t > tTxD, the TxD time-out function deactivates the transmission of the signal at the bus. This is realized to prevent the bus from being blocked permanently due to an error. The transmission is released again, after a mode state change. TxD to RxD Short Circuit Feature Similar to the TxD time-out, a TxD to RxD short circuit would also drive a permanent dominant signal at the bus and so block the communication. To avoid this, the TLE 6251 G has a TxD to RxD short circuit detection.

Reduced Electromagnetic Emission The bus driver has an implemented control to reduce the electromagnetic emission (EME). This is achieved by controlling the symmetry of the slope, resp. of CANH and CANL. Overtemperature The driver stages are protected against overtemperature. Exceeding the shutdown temperature results in deactivation of the driving stages at CANH/L. To avoid a bit failure after cooling down, the signals can be transmitted again only after a dominant to recessive edge at TxD. Figure 3 shows the way how the transmission stage is deactivated and activated again. First an overtemperature condition causes the transmission stage to deactivate. After the overtemperature condition is no longer present, the transmission is only possible after the TxD bus signal has changed to recessive level.

TLE 6251 G
Reception The analog CAN bus signals are converted into a digital signal at RxD via the differential input receiver. In normal mode and RxD only, the split pin is used to stabilize the recessive common mode signal. Permanent Recessive Clamping If the RxD signal is permanent recessive, although there is a message sent on the bus, the host C of this transceiver could start a message at any time, because the bus seems to be idle. To prevent this node to disturb the communication on the bus, the TLE 6251 G offers a so called permanent RxD recessive clamping. If the RxD signal is permanent recessive, an error flag is set and the transmitter is deactivated as long as the error occurs Receive Only Mode (RxOnly Mode) In the RxOnly mode, the transmission stage is deactivated but the reception of signals via the CAN bus is still possible. This mode is implemented to support hardware and software diagnosis functions. If there is an hardware error on the transmission part of a node (e.g. bubbling idiot failure), in the RxOnly mode, the bus is no longer blocked and the C can still receive the messages on the bus. It is also possible to make a network analysis of the interconnections between the nodes. A connection between two nodes (in a network) is checked if both nodes are in the normal mode and all others are in RxOnly mode. If a message from one node is sent to the other, this has to be acknowledged. If there is no acknowledge of the message, the connection between the two nodes has an error. The RxD pin also works as an diagnosis flag, which is described more in detail in Table 2.

TLE 6251 G
Standby Mode In the standby mode, transmission and reception of signals is deactivated. This is the first step of reducing the current consumption. The internal voltage regulator control pin (INH) is still active, so all external (INH controlled) powered devices are also activated. Wake-Up The wake-up is possible via WK-pin (filtering time t > tWK) or CAN message (filtering time t > tWU) and sets the RxD/NERR pins to LOW, see Figure 4. Now the C is able to detect this change at RxD and switch the transceiver into the normal mode. Once the wake-up flag is set (= LOW), it remains in this state, as long as the transceiver is not transferred into the normal mode. The detection of the wake-up source is possible during the first 4 recessive to dominant edges at TxD in the normal mode. Go-to Sleep Mode The go-to sleep mode is used to have an intermediate step between the sleep mode and all other modes. This mode has to control if the sleep command (EN = 1, NSTB = 0) is activated for a minimum hold time t > thSLP. Afterwards the TLE 6251 G automatically transfers into the sleep mode. The activated features in go-to sleep mode are similar to the standby mode. Sleep Mode In the sleep mode, transmission and reception of signals is deactivated. This is the second step of reducing the current consumption. The internal voltage regulator control pin (INH) is deactivated. Transition into other Modes during Sleep Mode Transition from sleep into other modes is possible if VCC and VC active. Selection of the modes can be done by the mode control inputs. Wake-Up The wake-up is possible via WK-pin (filtering time t > tWK) or CAN message (filtering time t > tWU) and automatically transfers the TLE 6251 G into the standby mode and sets the RxD/NERR pins to LOW, see Figure 4. Once the TLE 6251 G has been set to the standby mode, the system voltage regulator is activated by the inhibit output INH, and the C restarts. Now the C is able to detect this change at RxD and switch the transceiver into the normal mode. Once the wake-up flag is set (= LOW), it remains in this state, as long as the transceiver is not transferred into the normal mode. The detection of the wake-up source is possible during the first 4 recessive to dominant edges at TxD in the normal mode.

Split Circuit The split circuitry is activated during normal and RxOnly mode and deactivated (SPLIT pin high ohmic) during sleep and standby mode. The SPLIT pin is used to stabilize the recessive common mode signal in normal mode and RxOnly mode. This is realized with a stabilized voltage of 0.5 VCC at SPLIT.

Other Features
VC-level Adapter
The advantage of the adaptive C logic is the ratiometrical scaling of the I/O levels depending on the input voltage at the VC pin. So it can be ensured that the I/O voltage of the C fits to the internal logic levels of the TLE 6251 G. WAKE Input The wake-up input pin is a bi-level sensitive input. This means that both transitions, HIGH to LOW and LOW to HIGH, result in a wake-up.
VCC, VC Undervoltage Detection
If an undervoltage condition at VCC, VC is detected for longer than t = tUV,t, the TLE 6251 G automatically transfers into the sleep mode and the undervoltage flag is set. This flag is an internal flag and not available via NERR or RxD. The flag is cleared again, after setting the power on or wake flag (power-up or wake-up).
VS Undervoltage Detection
If an undervoltage condition at VS is detected, the TLE 6251 G immediately transfers into the standby mode and the undervoltage flag is set. This flag is an internal flag and not available via NERR or RxD. The flag is cleared again, after the supply voltage VS has reached the nominal value.
