AZV5002DS-7 Diodes Incorporated

AZV5002 Low Power Audio Jack Detector with SEND/END Detection in Miniaturized Package Description Pin Assignments The AZV5002 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 AZV5002 a microphone. S/E DET Pullup resistors for the detection pins are internalized, a built in resistor 7 6 divider provides the reference voltage for detecting the left audio GND DET S/E DET 8 5 channel. The logic low output of the OR gate indicates the headset has S/E REF 9 4 L DET been connected properly. VDD2 10 3 VDD The AZV5002 is available in miniaturized package, U-QFN1418-10 1 2 which helps reduce the space needed on PCB boards.
