Functional Range

Note:

Within the functional range the IC operates as described in the circuit description. The electrical

characteristics are specified within the conditions given in the related electrical characteristics

table.

Device Behavior Outside of Specified Functional Range:

• 28V < VS,func < 40V: Device is still functional (including the state machine); the specified electrical

characteristics might not be ensured anymore. The regulators VCC1/2 are working properly, however, a

thermal shutdown might occur due to high power dissipation. The specified SPI communication speed is

ensured; the absolute maximum ratings are not violated, however the device is not intended for

continuous operation of VS >28V. The device operation at high junction temperatures for long periods

might reduce the operating life time;

• VCAN < 4.75V: The undervoltage bit VCAN_UV is set in the SPI register BUS_STAT and the transmitter is

disabled as long as the UV condition is present;

• 5.25V < VCAN < 6.0V: CAN transceiver is still functional. However, the communication might fail due to out-

of-spec operation;

• VPOR,f < VS < 5.5V: Device is still functional; the specified electrical characteristics might not be ensured

anymore:

– The voltage regulators will enter the linear (RDS_On) operation mode ,

– A VCC1_UV reset could be triggered depending on the Vrtx settings,

– GPIO behavior depends on the respective configuration:

- HS/LS switches remain switched On as long as the control voltage is sufficient.

- An unwanted overcurrent shutdown may occur.

- OC shutdown bit set and the respective HS/LS switch will turn Off;

– FO output remains On if it was enabled before VS > 5.5V,

– The specified SPI communication speed is ensured.
