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.
