The AZV5001 is a low power and cost effective headset detection IC with a comparator with internal hysteresis, OR gate, and N−channel MOSFET integrated designed to detect the assertion of a headset with a microphone. Pull−up resistors for the detection pins are internalized, a built in resistor divider provides the reference voltage for detecting the left audio channel. The logic low output of the OR gate indicates the headset has been connected properly.

The AZV5001 is available in miniaturized package, DFN1210H4-6 which helps reduce the space needed on PCB boards.
