High Speed CAN Transceiver

Fail Safe Functions

Overtemperature Protection

The has an integrated overtemperature detection to protect the against thermal overstress of the

transmitter. The overtemperature protection is active in normal-operating mode and disabled in power-save

mode and receive-only mode. In case of an overtemperature condition, the temperature sensor will disable

the transmitter (see Figure 1) while the transceiver remains in normal-operating mode.

After the device has cooled down the transmitter is activated again (see Figure 8). A hysteresis is implemented

within the temperature sensor.

Delay Time for Mode Change

selected mode of operation, the RxD output pin is set to logical “high” during the mode change.

In this case the RxD output does not reflect the status on the CANH and CANL input pins (see as an example

Figure 12 and Figure 13).
