Low-Power Headset Detection IC in Miniaturized Package
ADVANCED INFORMATION
Description
Pin Assignments
AZV5001
The AZV5001 is a low-power and cost-effective headset detection IC
containing a comparator with internal hysteresis, OR gate, and
N−channel integrated MOSFET, designed to detect the insertion 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 is connected
properly.

Application Information
ADVANCED INFORMATION
Supply Voltage
The AZV5001 device is guaranteed to operate at supply voltage ultra low to 1.6V. For better performance, a power supply decoupling capacitor is
necessary, a minimum 0.1µF decoupling capacitor should be placed as close as possible to the V CC pin.
Audio Jack Detection
The AZV5001 is designed to simplify the detection of stereo audio connector with a microphone contact. When the headset is not connected, the
internal pull-up resistors on L_Detect and G_Detect pull those pins high. When the headset is connected to the switched audio jack, the headset
ground and left audio channel trigger L_Detect and G_Detect to logic low.
The AZV5001 can work with either the CITA 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.
MIC Pin Biasing
The AZV5001 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 1mV 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.
