U4791B Datasheet (TEMIC Semiconductors) - Automotive Lamp Outage Monitor/ VT = 53 mV

U4791B, Automotive Lamp Outage Monitor/ VT = 53 mV

The monolithic integrated bipolar circuit, U4791B, is designed as a monitor for lamp failure in automobiles.

The comparator threshold is matched to the PTC characteristic of incandescent lamps.

The threshold is tied to a typical value of V4,6 = VS * VT whereas VT = 53 mV.

The integrated circ
