AZV5001RA4-7

Audio Special Purpose Overview

The AZV5001RA4-7 is a low-power headset detection IC manufactured by Diodes Incorporated, designed for detecting the insertion of headsets with microphones. It integrates a comparator with internal hysteresis, an OR gate, and an N-channel MOSFET within a miniaturized X2-DFN1210-6 package. The device operates on a supply voltage range of 1.6V to 5.0V with a typical supply current of 7.5µA at VCC = 1.8V. Internal pull-up resistors are provided for detection pins, and a built-in resistor divider establishes the reference voltage for left audio channel detection. The logic low output indicates proper headset connection.

Audio Special Purpose Applications

• Mobile Phones
• Tablets
• Battery Powered Devices

Audio Special Purpose Procurement Notes

Verify the part number suffix -7 corresponds to the 5,000-unit tape and reel packaging configuration. Confirm the X2-DFN1210-6 package code RA4 matches the required footprint. Ensure compliance with RoHS and halogen-free requirements if specified for the application environment.

Audio Special Purpose Selection Notes

Select this component when space-constrained designs require integrated headset detection logic. The 1.6V minimum operating voltage suits battery-powered applications. Verify that the system's MIC bias voltage and pull-up resistor values align with the recommended 2.2kΩ configuration for optimal performance under the specific supply voltage conditions.

Audio Special Purpose Part Context

The AZV5001RA4-7 belongs to the AZV5001 series of low-power headset detection ICs. It is specifically engineered to simplify stereo audio connector detection with microphone contacts. The device supports both CITA and OMTP standards, though additional circuitry may be needed for simultaneous support. It replaces discrete logic solutions in mobile and portable audio devices.
