U4791B Datasheet Automotive Lamp Outage Monitor/ Vt = 53 Mv

Manufacturer: TEMIC Semiconductors (now Microchip)

Overview: U4791B Automotive Lamp Outage Monitor, VT = 53 mV.

General Description

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

The parator 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.
