General Description

The AS8520 is a companion IC for sensor and actuator LIN slaves.

The device provides application specific add-ons, such as the resistive attenuator for battery voltage sensing, a micro controller interface to control 2 relay drivers, to access control register, and diagnosis options.

The AS8520 has a window watchdog which can be enabled as a factory option.
