Product details
Overview
AZV3002RL-7 from Diodes Incorporated is a dual-channel, rail-to-rail input/output comparator with push-pull output stage, designed for low-voltage battery-powered systems. It operates from 1.6V to 5.5V, draws only 9µA typical supply current per channel, features 9mV typical internal hysteresis, and delivers 0.8µs typical propagation delay under 20mV overdrive - enabling precise, low-power threshold detection in space-constrained portable electronics.
For engineers reviewing the AZV3002RL-7 datasheet, AZV3002RL-7 pinout, AZV3002RL-7 application, or AZV3002RL-7 equivalent, this device is selected for ultra-low quiescent current, guaranteed operation down to 1.6V, no phase inversion at rail overdrive, and compatibility with 1.8V/3.0V/5.0V logic domains in mobile and IoT edge-sensing circuits.
Technical Context
The AZV3002RL-7 integrates two independent comparators sharing a common VCC and VEE supply, each with complementary P- and N-channel MOSFET output stages enabling true rail-to-rail output swing without external pull-ups. Its input stage supports common-mode voltage from VEE to VCC, eliminating phase inversion when inputs exceed supply rails.
Internal 9mV hysteresis provides noise immunity without external components, while propagation delay remains stable across 1.6–5.5V supply range and temperature (−40°C to +85°C). The U-FLGA1616-8 package supports high-density PCB layouts with thermal resistance θJA = 306°C/W and θJC = 122°C/W.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.6V to 5.5V - enables direct interface with 1.8V logic and legacy 3.3V/5V systems without level shifting. |
| Supply Current (per channel) | 9µA typical - extends battery life in always-on sensing nodes such as smoke detectors and wearable health monitors. |
| Propagation Delay | 0.8µs typical at 20mV overdrive - supports fast response in overvoltage/undervoltage protection circuits. |
| Input Offset Voltage | ±30mV max - ensures reliable trip-point accuracy in precision battery monitoring applications. |
| Hysteresis Voltage | 6–13mV - suppresses chatter in noisy environments like motor control feedback or industrial sensor interfaces. |
| Input Bias Current | 1pA typical - minimizes loading on high-impedance sources such as thermistors or photodiodes. |
| Output Structure | Push-pull CMOS - eliminates need for external pull-up resistors, reducing BOM count and board area. |
Pinout & Package
Package: U-FLGA1616-8 - 1.6mm × 1.6mm, 0.5mm pitch, bottom-side thermal pad, RoHS-compliant "Green" molding compound.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT1 | Rail-to-rail push-pull output of Comparator 1 - drives logic inputs directly without external biasing. |
| 2 | IN1− | Inverting input of Comparator 1 - accepts signals up to VCC or below VEE without phase inversion. |
| 3 | IN1+ | Non-inverting input of Comparator 1 - supports full rail-to-rail common-mode range for flexible reference design. |
| 4 | VEE | Negative supply terminal - tied to ground in single-supply configurations; enables true bipolar operation. |
| 5 | IN2+ | Non-inverting input of Comparator 2 - independently configurable for dual-threshold or window detection schemes. |
| 6 | IN2− | Inverting input of Comparator 2 - supports differential sensing or reference comparison with matched layout. |
| 7 | OUT2 | Rail-to-rail push-pull output of Comparator 2 - provides independent status signaling for fault isolation. |
| 8 | VCC | Positive supply terminal - powers both comparators and output stages; decoupling required within 2mm. |
Key Features
| Feature | Design Value |
|---|---|
| No phase inversion at rail overdrive | Input voltages exceeding VCC or falling below VEE do not invert output polarity - critical for robust battery voltage monitoring. |
| Internal 9mV hysteresis | Eliminates external hysteresis resistors in threshold-detection circuits, reducing component count and layout sensitivity. |
| Rail-to-rail I/O | Full input common-mode range (VEE to VCC) and output swing (VEE to VCC) simplify interfacing with mixed-voltage systems. |
| Ultra-low 9µA supply current | Enables multi-year operation from coin-cell batteries in wireless sensor nodes and portable medical devices. |
| Push-pull output stage | Drives capacitive loads up to 15pF directly; avoids shoot-through current and enables fast rise/fall times (10ns typ). |
Applications
| Smartphone Battery Protection | Wearable Heart Rate Monitor |
|---|---|
|
Use Scenario: Detecting overvoltage and undervoltage conditions during Li-ion charging cycles to prevent cell damage. IC Role / Device Role / Timing Role: Dual comparator implements independent high- and low-threshold detection with shared VCC/VEE and separate outputs for fault flagging.

Use Value: 0.8µs propagation delay enables sub-millisecond timing resolution; rail-to-rail input accommodates variable DC offset in analog front-end. |
| IoT Smoke Detector Sensor Interface | Industrial Temperature Threshold Alarm |
|
Use Scenario: Converting ionization chamber current into digital alarm signal using a transimpedance amplifier followed by threshold comparison. IC Role / Device Role / Timing Role: Comparator compares TIA output against reference voltage; internal hysteresis prevents false triggers from EMI-induced noise. Use Value: 1pA input bias current avoids loading high-impedance TIA output; 9mV hysteresis rejects broadband RF interference. |
Use Scenario: Monitoring thermistor voltage divider output to trigger fan control or shutdown when temperature exceeds safe limits. IC Role / Device Role / Timing Role: Dual comparator implements window detection: OUT1 asserts above upper limit, OUT2 asserts below lower limit. Use Value: Independent inputs allow precise hysteresis tuning per threshold; 5.5V max supply supports direct connection to 5V industrial power rails. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual low-voltage comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV3702DR | Higher supply current (1.8µA per channel), no internal hysteresis, SO-8 only | Requires external hysteresis resistors; less suitable for ultra-low-power battery designs | Prefer when external hysteresis tuning is needed and board space permits SO-8 footprint |
| MAX9062ASA+ | Wider supply range (1.8–5.5V), 12µA supply current, rail-to-rail output only (not input) | Limited input common-mode range excludes VEE-to-VCC sensing; higher quiescent draw reduces battery life | Choose when input rail-to-rail is not required and higher drive strength (20mA sink/source) is prioritized |
Compared with TLV3702DR and MAX9062ASA+, the AZV3002RL-7 uniquely combines 1.6V operation, rail-to-rail input *and* output, internal hysteresis, and sub-10µA supply current - making it optimal for miniaturized, long-life battery systems where every nanoamp and millivolt matters.

FAQ
Does AZV3002RL-7 require external hysteresis resistors?
No. The AZV3002RL-7 integrates 6–13mV internal hysteresis, eliminating the need for external resistor networks in most threshold-detection applications. This simplifies PCB layout, reduces component count, and improves consistency across temperature and process variation. External hysteresis can still be added via positive feedback if wider trip windows are required.
Can AZV3002RL-7 operate with a single 1.8V supply?
Yes. The AZV3002RL-7 is fully specified from 1.6V to 5.5V supply voltage, including operation at 1.8V. At 1.8V, it maintains rail-to-rail input common-mode range (0V to 1.8V), 0.8µs typical propagation delay, and 9µA typical supply current - making it ideal for modern ultra-low-voltage microcontroller interfaces.
What is the maximum capacitive load the push-pull output can drive?
The AZV3002RL-7 push-pull output is characterized with CL = 15pF in AC specifications, delivering 10ns typical transition times at 5.5V. While not explicitly rated for higher capacitance, stable operation up to 50pF is achievable with minor propagation delay increase (<1.2µs), provided adequate local VCC decoupling (100nF ceramic) is used within 2mm of the package.
Is the U-FLGA1616-8 package compatible with standard reflow profiles?
Yes. The U-FLGA1616-8 package is lead-free and RoHS-compliant, qualified for IPC/JEDEC J-STD-020D moisture sensitivity level 1 (MSL1), and compatible with standard Pb-free reflow profiles (peak temperature ≤260°C, time above liquidus 60–90 seconds). Thermal pad soldering requires controlled stencil aperture (70–80% coverage) and flux selection per Diodes AP02002 guidelines.
