8-pin LIN companion IC

Buy Now Order Sample

The AS8530 is a power management and communication device for LIN sensor and actuator slaves. It provides a LIN transceiver, a voltage regulator, a 2-wire microcontroller interface through shared pins to communicate configuration, diagnostic and status data to the micro controller, to trigger a window watchdog and to access 8 backup registers, all in an 8-pin SOIC package. The addition of enhanced diagnosis functions provides built-in support for the requirements of ISO26262. The AS8530 has passed successfully the Lin 2.1 Conformance Test.
