NEW PRODUCT 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. 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  Supply Voltage Range: 1.6~5.5V  Comparator, OR Gate, N-Channel MOSFET Integrated  Open Drain Output for MIC Pin  U-QFN1418-10: Available in “Green” Molding Compound (No Br. Sb.)  Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2)  Halogen and Antimony Free. “Green” Device(Note 3) Pin Assignments AZV5002 S/E DET S/E_DET 8 7 6 5 S/E_REF 9 4 VDD2 10 1 GND 2 MIC 3 Top View (U-QFN1418-10) Fig. 1 GND_DET L_DET VDD Applications  Mobile Phones  Tablet  Battery Powered Devices  Alarm and Security Systems Notes: 1.

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 0.1F 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. Functional Block Diagram AZV5002 S/E_REF S/E_DET VDD2 VDD VDD 270K 1M VDD 1M VDD VDD 1M L_DET GND GND_DET Fig.3 S/E MIC DET AZV5002 Document number: DS38465 Rev. 1 - 2 3 of 15 www.diodes.com March 2016 © Diodes Incorporated NEW PRODUCT Absolute Maximum Ratings (@TA = +25°C, unless otherwise specified.)
