U4790B General Description

The bipolar IC U4790B 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 where VT = 8 mV. If the voltage drop across shunt resistor, Rsh, exc.
