AZV5002 Low Power Audio Jack Detector with SEND/END Detection in Miniaturized Package Description Pin Assignments NEW PRODUCT 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. AZV5002 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.

VDD should be powered up before VDD2. The send/end detection comparator will not be functional unless VDD and VDD2 are both applied. VDD2 can be connected to VDD or to a separate supply voltage, such as the MIC bias voltage. Decoupling capacitors of 0.1uF should be placed as close as possible to each power supply pin. NEW PRODUCT Audio Jack Detection TheAZV5002 is designed to simplify the detection of a stereo audio connector with a microphone contact. When the headset is not connected, the internal pull−up resistors on L_DET and GND_DET pull those pins high. When the headset is connected to the switched audio jack, the headset ground and left audio channel trigger L_DET and GND_DET to logic low. The AZV5002 can work with either the CTIA or OMTP standard. In order to support both standards simultaneously, a cross point switch and additional circuitry is necessary to detect and swap the ground and microphone pins. Send/End Button Press Detection A second integrated comparator allows the send/end signal to be compared with a reference voltage to detect whether the send/end button has been pressed. MIC Pin Biasing The AZV5002 typical application circuit in Figure 2 shows the recommended 2.2KΩ pull-up resistor to the MIC bias voltage under supply voltage 1.8V condition. While the headset is not detected, the internal NMOS transistor is enabled to mute the MIC signal. If the MIC sink current is 1mA under system application, the MIC pin is pulled near 5.5mV when the headset is not present. The internal NMOS transistor is optimized to sink up to 2mA of current, allowing some flexibility in the selection of the pull-up resistor and MIC bias voltage.
