Product details
Overview
AZV5001RA4-7 from Diodes Incorporated is a low-power headset detection IC integrating a comparator with hysteresis, dual-input OR gate, and N-channel MOSFET in a DFN1210-6 package. It detects stereo headset insertion with microphone via simultaneous L_Detect and G_Detect logic-low assertion, delivers 7.5µA typical supply current at 1.8V, supports 1.6–5.0V operation, and drives MIC with open-drain output for send/end detection in mobile audio jacks.
For engineers reviewing the AZV5001RA4-7 datasheet, AZV5001RA4-7 pinout, AZV5001RA4-7 application, or AZV5001RA4-7 equivalent, key selection considerations include its ultra-low ICC, integrated pull-up resistors on detection pins, internal voltage divider for left-channel reference, open-drain MIC output with <1.4Ω RDS(on), and compatibility with both OMTP and CTIA jack standards.
Technical Context
The AZV5001RA4-7 implements a dual-input detection architecture where OUT asserts logic low only when both G_Detect and L_Detect fall below their respective input thresholds (0.63V and 1.33V at VCC = 1.8V). Its internal comparator includes hysteresis to reject noise during plug-in/out transients, and the integrated NMOS sink on MIC supports up to 2mA current with sub-1mV VOL under 1mA load.
Operation relies on external 2.2kΩ pull-up to MIC bias voltage and internal resistor divider for L_Detect reference; no external components are required for G_Detect or L_Detect biasing. The OR gate combines detection signals with propagation delays of ≤480ns (L_Detect path) and ≤10ns (G_Detect path), enabling fast, deterministic headset presence confirmation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Current | 7.5µA typical at 1.8V - enables multi-year battery life in always-on detection circuits |
| Supply Voltage Range | 1.6V to 5.0V - supports direct interface with 1.8V/2.8V/3.3V/5.0V system rails without level shifters |
| Output Logic | Open-drain OUT with VOL ≤ 0.1V at 0.1mA - directly interfaces with baseband GPIOs requiring active-low headset detect |
| MIC Sink Capability | RDS(on) = 0.9–1.4Ω at 1mA - ensures <1mV residual voltage on MIC line when headset absent, minimizing false send/end triggers |
| Detection Thresholds | G_Detect VIL ≤ 0.63V, L_Detect VIL ≤ 1.33V at 1.8V - guarantees reliable detection across OMTP (GND/MIC swap) and CTIA (MIC/GND fixed) jack configurations |
| Propagation Delay | ≤10ns (G_Detect path), ≤480ns (L_Detect path) - enables sub-microsecond detection response for real-time audio routing decisions |
Pinout & Package
Package: DFN1210-6 (X2-DFN1210-6), 1.20 × 1.00 × 0.40 mm, thermally enhanced exposed pad, RoHS-compliant "Green" molding compound.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND (Pin 1) | Negative power supply reference | System ground connection; must be low-impedance return path for MIC sink current and detection logic |
| MIC (Pin 2) | Open-drain microphone signal control | Sinks up to 2mA to mute MIC when headset absent; requires external 2.2kΩ pull-up to bias voltage |
| G_Detect (Pin 3) | Ground contact detection input | Asserts low when headset ground shorts to system ground; threshold ≤0.63V enables OMTP/CTIA compatibility |
| L_Detect (Pin 4) | Left audio channel detection input | Asserts low when left channel shorts to ground; internal resistor divider sets reference for CTIA-standard detection |
| VCC (Pin 5) | Positive power supply | 1.6–5.0V input; requires ≥0.1µF ceramic decoupling capacitor placed adjacent to pin |
| OUT (Pin 6) | Headset presence logic output | Active-low open-drain signal; goes low only when both G_Detect and L_Detect are simultaneously low |
Key Features
| Feature | Design Value |
|---|---|
| Integrated detection logic | Comparator + OR gate eliminates need for external logic gates or microcontroller polling |

Equivalent & Alternatives
The following parts are listed as comparable options for similar headset detection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX14689EWA+T | Higher ICC (15µA typ), requires external pull-ups, no integrated L-channel reference divider | Lacks native CTIA/OMTP auto-detection; needs external resistor network and GPIO coordination | Select when existing design uses MAXIM ecosystem and can accommodate higher current and external components |
| TLV320AIC3104IRHBR | Audio codec with integrated headset detect (not dedicated IC); ICC = 1.2mA in headset-detect mode | Combines detection with full audio path; occupies larger QFN40 package and consumes significantly more power | Select only when full audio processing is required alongside detection - not suitable for standalone low-power monitoring |
Compared with MAX14689EWA+T and TLV320AIC3104IRHBR, the AZV5001RA4-7 delivers the lowest power consumption (7.5µA), smallest footprint (1.2×1.0mm), and highest integration (internal pull-ups, L-reference divider, MOSFET) - making it optimal for space- and battery-constrained portable devices needing dedicated, reliable headset detection.

FAQ
What is the minimum supply voltage required for reliable operation of the AZV5001RA4-7?
The AZV5001RA4-7 operates reliably down to 1.6V per its Recommended Operating Conditions table. At this voltage, all specifications-including detection thresholds, propagation delays, and MIC RDS(on)-remain within guaranteed limits. Below 1.6V, functionality is not characterized and may result in incomplete detection or increased ICC variation.
Does the AZV5001RA4-7 require external pull-up resistors on L_Detect and G_Detect pins?
No. Internal pull-up resistors are integrated on both L_Detect and G_Detect pins, eliminating the need for external components. This is explicitly stated in the device description and confirmed in the Functional Block Diagram and Pin Descriptions sections of the datasheet.
How does the AZV5001RA4-7 support both OMTP and CTIA headset standards?
It supports OMTP and CTIA by detecting ground continuity on G_Detect and left-channel continuity on L_Detect - both required for valid headset presence. Since OMTP swaps MIC and GND while CTIA keeps them fixed, the dual-pin logic ensures correct detection regardless of pinout, provided the host system routes G_Detect to the jack's ground contact and L_Detect to the left channel contact.
What is the maximum sink current capability of the MIC pin, and what is the resulting voltage drop at 1mA?
The MIC pin's integrated N-channel MOSFET has an RDS(on) of 0.9–1.4Ω. At 1mA sink current, the resulting voltage drop is 0.9–1.4mV - well below the 1mV threshold cited in the Application Information section for reliable send/end detection under typical 2.2kΩ pull-up conditions.
