Additional Details

The MC33972TEW/R2 is designed to operate in harsh automotive environments and is qualified to AEC-Q100 standards. It features low quiescent current consumption to minimize power drain when the system is in standby mode. The watchdog timer can be configured to reset the microcontroller if it detects a software fault. The fail-safe output can be used to disable critical functions in the event of a system failure. The operating temperature range is -40°C to 125°C. It is supplied in a thermally enhanced package. The CAN transceiver supports data rates up to 1 Mbit/s, and the LIN transceiver supports data rates up to 20 kbit/s.
