In Sleep mode the power supply
the CAN bus or the local Wake - Up pin, shifts the device from Sleep Mode into Stand - By Mode.
The following operations mode are available on the TLE6251-2G:
•
•
•
•
•
Depending on the operation mode, the output driver stage, the receiver stage, the split termination and the bus
biasing are active or inactive.

In Normal Operation Mode the HS CAN transceiver TLE6251-2G sends the serial data stream on the TxD pin to
the CAN bus while at the same time the data available on the CAN bus is monitored on the RxD output pin. In
Normal Operation Mode all functions of the TLE6251-2G are active:
•
•
•
•
•
•
•
•
•
•
The HS CAN transceiver TLE6251-2G enters Normal Operation Mode by setting the mode selection pins EN and
NSTB to logical “High” (see
5.2
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:
•

The output driver stage is active and drives data from the TxD to the CAN bus.
The normal receiver unit is active and provides the data from the CAN bus to the RxD pin.
The low power receiver and the bus Wake - Up function is inactive.
The local Wake-Up pin is disabled.
The INH pin is connected to
The RxD pin is “Low” for a “Dominant” bus signal and “High” for a “Recessive” bus signal”
The SPLIT pin is set to
The bus basing is set to
The failure detection is active and failures are indicated at the NERR pin. (see
The undervoltage detection on the all 3 power supplies
The output driver stage is disabled and data which is available on the TxD pin will be blocked and not
communicated to the CAN bus.
The normal receiver unit is active and provides the data which is available on the CAN bus to the RxD pin.
The INH pin is connected to
The RxD pin is “Low” for a “Dominant” bus signal and “High” for a “Recessive” bus signal.
