AZV5002
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.
Pullup 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.

Function
Connects to system ground.
MIC output pin with open drain output type. When the headset is asserted, then MIC is pulled up to
the MIC bias voltage with a pull-up resistor. When the headset is not asserted, then MIC is pulled
low.
System power supply. A bypass capacitor of 0.1F is recommended as close as possible to the pin.
Left channel detection pin. Connect to audio jack L_DET, this pin is pulled low when the headset is
present.
Ground pin detection pin. Connect to audio jack GND_DET, this pin is pulled low when the headset
is present.
DET is a logic output that indicates whether the headset has been properly inserted.
S/E is an output port indicates SEND/END button condition. When SEND/END button press is
detected, S/E output is at low level.
Non-inverting input of the comparator detects whether the SEND/END button has been pressed.
Inverting input of the comparator to set a voltage reference with an external resistor divider.
System power supply for the S/E detection comparator. A bypass capacitor of 0.1F is
recommended as close as possible to the pin.
