Automotive Lamp-outage Monitor IC

U479B Features

* 2-kV ESD Protection Two Comparators with Common Reference Tight Threshold Tolerance Threshold Matched to PTC Characteristic of Incandescent Lamps Temperature Compensated NPN Output Interference and Da

U479B General Description

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 where VT = 8 mV. If the voltage drop across the shunt resistor, Rsh.
