U2481B, (U2481B / U2482B) Automotive Lamp Outage Monitor

The U2481B and the U2482B multicomparator circuits are designed to monitor automotive illumination by sensing the voltage drop across shunt resistors.

Provided with extremely low comparator thresholds, these ICs can be used together as a chip set to build an entire lamp monitor system.
