TLE8251V High Speed CAN Transceiver with Bus Wake-up Functional Description 4.3.5 Undervoltage on the Transmitter Supply V In case the transmitter supply V falls below the threshold V < V , the transceiver TLE8251VSJ changes CC(UV,F) the mode of operation to forced stand-by mode. The transmitter and also the normal-mode receiver of the TLE8251VSJ are powered by the V supply. -
Page 13: Remote Wake-Up
TLE8251V High Speed CAN Transceiver with Bus Wake-up Functional Description Remote Wake-up The TLE8251VSJ has a remote wake-up feature, also called bus wake-up feature. In both stand-by mode and forced stand-by mode, the low-power receiver monitors the activity on the CAN bus and in case it detects a wake-up signal, the TLE8251VSJ indicates the wake-up signal on the RxD output pin. -
Page 14: Fail Safe Functions
TLE8251V High Speed CAN Transceiver with Bus Wake-up Fail Safe Functions Fail Safe Functions Short Circuit Protection The CANH and CANL bus outputs are short circuit proof, either against GND or a positive supply voltage. A current limiting circuit protects the transceiver against damage. If the device is heating up due to a continuous short on the CANH or CANL, the internal overtemperature protection switches off the bus transmitter. -
Page 15: Overtemperature Protection
TLE8251V High Speed CAN Transceiver with Bus Wake-up Fail Safe Functions Overtemperature Protection The integrated overtemperature detection protects the TLE8251VSJ against thermal overstress of the transmitter.
