Modes of Operation

5.3

Stand-by Mode

Stand-by Mode is a low power mode of the TLE9255W with both the transmitter and the receiver disabled. In

Stand-by Mode the transceiver can neither send data to the HS CAN bus nor can it receive data from the

HS CAN bus:

• The transmitter is disabled and the data available on the TxD input is blocked.

• The RxD output pin indicates a wake-up event (Chapter 5.8). If no wake-up event is pending, then the

default value of the RxD output pin is “high”.

• After Power on Reset the bus biasing is off. Chapter 5.6 describes the conditions for the bus biasing.

• The TxD timeout function is disabled (Chapter 6.4).

• The overtemperature protection is disabled (Chapter 6.5).

• The undervoltage detection on VBAT is enabled(Chapter 6.2.1)

• The undervoltage detection on VCC is enabled (Chapter 6.2.2).

• The undervoltage detection on VIO is enabled (Chapter 6.2.4).

• The INH output pin is “high”.

• If the selective wake function is disabled (SWK_EN = 0), then the HS CAN bus is continuously monitored for

a valid wake-up pattern (Chapter 5.7.1). If the selective wake function is enabled, then a valid wake-up

pattern is not signalled in the SPI bit WUP.

• Only if the selective wake function is enabled (SWK_EN = 1), then the HS CAN bus is continuously

monitored for a valid WUF (Chapter 5.7.2).

• Local wake-up function is enabled (Chapter 5.7.3).

•If VIO > VIO_UV, then a mode change is possible.
