... AEC Qualified Description As a successor of the TLE6251G, the TLE6251-3G is designed to provide an excellent passive behavior in Power Down. This feature makes the TLE6251-3G extremely suitable for mixed power supply HS-CAN networks. The TLE6251-3G 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 TLE6251-3G 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 ...

... HS CAN transceiver TLE6251-3G has a receive unit and a output stage, allowing the transceiver to send data to the bus medium and monitor the data from the bus medium at the same time. The HS CAN TLE6251-3G converts the serial data stream available on the transmit data input TxD into a differential output signal on CAN bus. The differential output signal is provided by the pins CANH and CANL. The receiver stage of the TLE6251-3G monitors the data on the CAN bus and converts them to a serial data stream on the RxD pin. A logical “ ...

... Operation Modes Five different operation modes are available on TLE6251-3G. 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. Both digital input pins are event triggered. depending on the status of the EN and NSTB pins. A mode change via the mode selections pins EN and NSTB is only possible if the power supplies EN -> ...

... Table 2 5.2 Receive-Only Mode The Receive-Only mode can be used to test the connection of the bus medium. The TLE6251-3G can still receive data from the bus, but the output stage is disabled and therefore no data can be sent to the CAN bus. All other functions are active: • ...

... The failure diagnostic is active and local failures are indicated at the NERR pin (see • The under-voltage detection on the all 3 power supplies The HS CAN transceiver TLE6251-3G enters Receive-Only mode by setting the EN pin to logical “Low” and the NSTB to logical “High” (see Table 2 5 ...
Page 12
... Sleep Mode The Sleep mode is a power save mode. In Sleep mode the current consumption of the TLE6251-3G is reduced to a minimum while the device is still able to Wake- message on the CAN bus or a local Wake-Up event on the pin WK. Most of the functions of the TLE6251-3G are disabled: • ...

... 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 TLE6251-3G enters into Stand-By mode and the INH pin remains connected to the hSLP V 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 TLE6251-3G 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 TLE6251-3G 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 “ ...

... According to the mode diagram in Receive-Only mode, Normal Operation mode. 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 “High” the TLE6251-3G changes from Sleep mode to Normal Operation mode (see The pins EN and NSTB have a hysteresis between the 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 TLE6251-3G 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 TLE6251-3G, 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: • ...

... RxD pin and set the local error flag. In order to avoid any data collisions on the CAN bus the output driver stage gets disabled. In Receive-Only mode the TLE6251-3G indicates the RxD Clamping by a logical “Low” signal on the NERR pin. The TLE6251-3G releases the failure flag and the output driver stage by a operation mode change or if the RxD clamping failure disappears. ...

... Under-Voltage Detection The TLE6251-3G provides a power supply monitoring on all three power supply pins: an under - voltage event on any of this three power supplies, the TLE6251-3G changes the operation mode and sets an internal failure flag. The internal failure flag is not indicated by the NERR output pin. ...

... Under-Voltage Event under-voltage event is detected at the power supply Stand-By mode, regardless of the operation mode in which the TLE6251-3G 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. ...
