U2480B Datasheet (TEMIC) - Automotive Lamp Outage Monitor

U2480B, Automotive Lamp Outage Monitor

The IC U2480B is designed for individual monitoring of 11 lamps in automobiles.

Three double comparators and five single comparators, which can be optionally interconnected, permit realization of many monitoring variants.

An integrated latch is available to memorize the outage of indicator or brake
