Low Power Audio Jack Detector with
SEND/END Detection in Miniaturized Package
Description
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
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 AZV5002 is available in miniaturized package, U-QFN1418-10
which helps reduce the space needed on PCB boards.
Features
Low Supply Current: 5µA (Typical) @ VDD = 1.8V
