... AEC Qualified Description As a successor of the TLE6251G, the TLE6251-2G is designed to provide an excellent passive behavior in Power Down mode. This feature makes the TLE6251-2G extremely suitable for mixed supply CAN networks. The TLE6251-2G provides different operation modes with a very low quiescent current in Sleep Mode. Based on the high symmetry of the CANH and CANL signals, the TLE6251-2G provides a very low level of electromagnetic emission (EME) within a broad frequency range ...

... The CAN transceiver is part of the physical layer specification. Several different physical layer standards of CAN networks have been developed over the last years. The TLE6251- High Speed CAN transceiver with dedicated Wake - Up functions. High Speed CAN Transceivers with Wake - Up functions are defined by the international standard ISO 11898-5 ...

... CAN bus. The differential output signal is provided by the pins CANH and CANL. The receiver stage of the TLE6251-2G monitors the data on the CAN bus and converts them to a serial data stream on the RxD pin. A logical “Low” signal on the TxD pin creates a “Dominant” signal on the CAN bus, followed by a logical “Low” signal ...

... Operation Modes Five different operation modes are available on TLE6251-2G. Each mode with specific characteristics in terms of quiescent current, data transmission or failure diagnostic. For the mode selection the digital input pins EN and NSTB are used. Figure 4 illustrates the different mode changes depending on the status of the EN and NSTB pins ...

... Receive - Only Mode The Receive - Only Mode can be used to test the connection of the bus medium. The TLE6251-2G can still receive data from the bus, but the output driver stage is disabled and therefore no data can be sent to the CAN bus. All other functions are active: • ...
Page 11
... Stand - By Mode After the power - up sequence the TLE6251-2G enters automatically into Stand - By Mode. Stand - By Mode is an idle mode of the TLE6251-2G with optimized power consumption. In Stand - By Mode the TLE6251-2G can not send or receive any data. The output driver stage and the normal receiver unit are disabled. Both CAN bus pins, CANH and CANL are connected to GND and the Split termination output is floating ...

... Sleep Command The Sleep command is a transition mode allowing external circuitry like a microcontroller to prepare the ECU for the Sleep mode. The TLE6251-2G stays in the Sleep command for the maximum time after exceeding the time the device changes into Sleep Mode. A mode change into Sleep Mode is only h(min) possible via the Sleep command ...
Page 13
... NSTB pin was set to logical “Low”. Important for the mode selection is the timing between the falling edge of the NSTB signal and the EN signal. If the logical signal on the EN pin goes low before the transition time t t < has been reached, the TLE6251-2G enters into Stand-By Mode and the INH pin remains connected to h(min) V the supply. In the case the logical signal on the EN pin goes low after the transition time t > ...

... In case the time of the “Dominant” signal on the CAN bus is shorter than the filtering time occurs. The filter time is implemented to protect the HS CAN transceiver TLE6251-2G against unintended bus Wake - Up’s, triggered by spikes on the CAN bus. The signal change on the CAN bus from “Recessive” to “ ...
Page 15
... Local Wake - Up The TLE6251-2G can be activated from Sleep Mode by a signal change on the WK pin, also called local Wake - Up. Designed to withstand voltages up to 40V the WK pin can be directly connected to the WK pin works bi-sensitive, meaning the Wake - Up logic on the pin WK triggers on a both signal changes, from “ ...
Page 16
... Mode Change via the EN and NSTB pin Besides a mode change issued by a Wake - Up event, the operation mode on the TLE6251-2G can be changed by changing the signals on the EN and NSTB pins. Therefore the power supplies According to the mode diagram in Receive - Only Mode, Normal Operation Mode and to the Sleep Command. A change from Sleep Mode direct to Stand-By Mode is only possible via a Wake - Up event. For example by setting the NSTB pin and the EN pin to logical “ ...

... CAN bus, a logical “Low” on the NERR pins indicates the CAN bus failure. For the failure indication the “Dominant” bits require a minimum pulse width of 4 µs. In case the TLE6251-2G detects an CAN bus failure, the failure is only indicated by the NERR pin, the transceiver doesn’t stop or block the communication, by disabling the output stage for example ...
Page 18
... Local Failures If a local failure occurs during the operation of the TLE6251-2G, the devices sets an internal local failure flag. The local failure flag can be displayed to the microcontroller during the Receive - Only Mode and the failures are indicated by a logical “Low” signal on the NERR pin. The following local failures can be detected: • ...

... TxD and the RxD pin, disables the output driver stage and sets the internal local failure flag. In Receive - Only Mode the TLE6251-2G indicates the TxD to RxD short by a logical “Low” signal on the NERR pin. The TLE6251-2G releases the failure flag and the output driver stage by an operation mode change from Receive - Only Mode to Normal Operation Mode ...

... Under - Voltage Detection The TLE6251-2G provides a power supply monitoring on all three power supply pins: an under - voltage event on any of this three power supplies, the TLE6251-2G changes the operation mode and sets an internal failure flag. The internal failure flag is not indicated by the NERR output pin. ...

Under - Voltage on 7.3.2 Under - Voltage Event under - voltage event is detected at the power supply Stand - By Mode, regardless of the operation mode in which the TLE6251-2G might currently operate. After the V power supply has been reestablished, the operation mode can be changed by applying a logical “High” signal S to the EN pin or the NSTB pin ...

Connecting the IO voltage of the microcontroller fits to the internal logic levels of the TLE6251-2G. 7.5 Split Circuit The SPLIT output pin is activated during Normal Operation Mode and Receive - Only Mode and deactivated (SPLIT pin high ohmic) during Sleep Mode and Stand - By Mode. The SPLIT pin is used to stabilize the recessive common mode signal in Normal Operation Mode and Receive - Only Mode ...
