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
5.3
After the power-up sequence the TLE6251-3G enters automatically into Stand-By mode. Stand-By mode is an idle
mode of the TLE6251-3G with optimized power consumption. In Stand-By mode the TLE6251-3G 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. The following functions are available in Stand-By mode:

Data Sheet
The low power receiver and the bus Wake-Up function is inactive.
The local Wake-Up pin WK is disabled.
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 output stage is disabled.
The normal receiver unit is disabled.
The low power receiver is active and monitors the CAN bus. In case of a message on the CAN bus the
TLE6251-3G sets an internal Wake-Up flag. If the power supplies

The TxD pin is disabled
The failure diagnostic is disabled.
The under-voltage detection on the all 3 power supplies
The TLE6251-3G detects a Power-Up event and indicates it at the NERR pin (see
After the start-up sequence the device enters per default Stand-By mode. Mode changes are only possible if

The device is in Sleep mode and a Wake-Up event occurs.
The device is in the Go-To-Sleep command and the EN pin goes low before the time t <
The device is in Normal Operation mode or Receive-Only mode and the EN pin and NSTB pin are set to logical
“Low”.
