ÿ Enhanced diagnosis capability via SPI
cuits, ground loss) and overtemperature condition. An interrupt
signal is generated whenever the failure status changes.
ÿ Protection against overload damage by current with interrupt generation
limitation and overtemperature detection
ÿ Bus driver outputs withstand – 27 V / + 40 V DC The device supports normal and standby modes and provides
remote wake up capability via bus line. The output (INH) can be
used to control an external voltage regulator.
