U479B, Automotive Lamp Outage Monitor/ VT = 8 mV

The monolithic integrated bipolar circuit, U479B, 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 V4,6 = VS * VT whereas VT = 8 mV.

If the voltage drop across shunt resisto
