Product details
Overview
AZV3002S-13 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, and delivers 0.8µs typical propagation delay under 20mV overdrive - enabling precise, low-power voltage monitoring in portable electronics.
For engineers reviewing the AZV3002S-13 datasheet, AZV3002S-13 pinout, AZV3002S-13 application, or AZV3002S-13 equivalent, key selection criteria include its dual-channel push-pull output architecture, internal 9mV hysteresis, no-phase-inversion input behavior, and SO-8 package compatibility with legacy 5V/3.3V/1.8V designs.
Technical Context
The AZV3002S-13 integrates two independent comparators sharing a common VCC and VEE supply, each featuring complementary P- and N-channel MOSFET output stages that enable true rail-to-rail output swing without external pull-ups. Its input stage supports common-mode voltages from VEE to VCC, eliminating phase inversion even when inputs exceed supply rails.
Internal 9mV (typ) hysteresis ensures noise immunity in noisy environments, while 1pA typical input bias current minimizes loading on high-impedance sensor sources. Propagation delay remains stable across 1.6–5.5V supply range, and supply current increases less than 1µA up to 1kHz output transition frequency - critical for extended battery life.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.6V to 5.5V - supports direct operation in 1.8V, 3.0V, and 5.0V systems without level-shifting. |
| Supply Current (dual) | 9µA typ - enables multi-year battery life in always-on sensing nodes. |
| Propagation Delay | 0.8µs typ at 20mV overdrive - provides fast response for threshold detection in real-time monitoring. |
| Input Hysteresis | 9mV typ - suppresses chatter from EMI or sensor noise without external components. |
| Input Bias Current | 1pA typ - preserves signal integrity when interfacing with high-Z sources like thermistors or photodiodes. |
| Rail-to-Rail I/O | Fully supported - allows full dynamic range utilization of ADC references or logic thresholds. |
| Output Structure | Push-pull CMOS - eliminates need for external pull-up resistors, reducing BOM count and board space. |
Pinout & Package
Package: SO-8 (Small Outline Integrated Circuit, 150mil width), RoHS-compliant, green molding compound, lead-free.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT1 | Comparator 1 active-high/low push-pull output - drives logic inputs or LED anodes directly. |
| 2 | IN1− | Inverting input of Comparator 1 - accepts reference or feedback signal for threshold comparison. |
| 3 | IN1+ | Non-inverting input of Comparator 1 - connects to monitored voltage or sensor output. |
| 4 | VEE | Negative supply rail (typically GND) - shared return path for both comparators and output stage. |
| 5 | IN2− | Inverting input of Comparator 2 - enables independent second threshold detection (e.g., under/over-voltage). |
| 6 | IN2+ | Non-inverting input of Comparator 2 - supports dual-sensor monitoring or window comparator configuration. |
| 7 | OUT2 | Comparator 2 active-high/low push-pull output - provides redundant or complementary alert signaling. |
| 8 | VCC | Positive supply rail (1.6–5.5V) - powers both comparators and output drivers with single rail. |
Key Features
| Feature | Design Value |
|---|---|
| No phase inversion | Input common-mode range extends beyond VCC/VEE rails - prevents false triggering during power-up or transient overvoltage. |
| Internal hysteresis | 9mV typical - eliminates need for external hysteresis resistors in most battery-monitoring applications. |
| Rail-to-rail output | Swings within 40mV of VCC and VEE at 5mA load - ensures clean TTL/CMOS logic-level compatibility. |
| Ultra-low quiescent current | 9µA total for dual channel - reduces standby power in always-on IoT edge sensors by >50% vs. legacy comparators. |
| SO-8 footprint | Pins 1–8 match industry-standard SOIC-8 layout - enables drop-in replacement in existing designs without PCB rework. |
Applications
| Smartphone Battery Monitoring | Wearable Health Sensor Interface |
|---|---|
|
Use Scenario: Detecting battery over-voltage (≥4.3V) and under-voltage (≤3.0V) thresholds in lithium-ion packs. IC Role / Device Role / Timing Role: Dual comparator implements independent high/low voltage trip points with internal hysteresis to prevent oscillation near thresholds. Use Value: Eliminates external hysteresis resistors and pull-ups, reducing component count by 4 parts per channel while maintaining ±15mV trip accuracy over temperature. |
Use Scenario: Converting analog photoplethysmography (PPG) sensor outputs into digital pulse edges for heart-rate calculation. IC Role / Device Role / Timing Role: Comparator 1 detects rising PPG peaks; Comparator 2 triggers on falling edge - enabling precise inter-beat interval measurement. Use Value: 0.8µs propagation delay ensures sub-millisecond timing resolution, and 1pA input bias avoids loading high-impedance transimpedance amplifier outputs. |
| Industrial Smoke Detector Threshold Logic | USB-C Power Delivery Status Monitoring |
|
Use Scenario: Comparing ionization chamber current against dual thresholds to distinguish smoke presence from humidity drift. IC Role / Device Role / Timing Role: Dual comparator with rail-to-rail inputs monitors differential chamber voltage; internal hysteresis rejects 50/60Hz EMI. Use Value: 1.6V minimum operating voltage allows direct use with single-cell LiFePO₄ backup batteries, extending alarm runtime during AC failure. |
Use Scenario: Validating CC1/CC2 line voltages during USB-C cable insertion to determine orientation and source capability. IC Role / Device Role / Timing Role: Comparator 1 monitors CC1 for Rp/Rd detection; Comparator 2 checks CC2 - enabling fast, deterministic port configuration. Use Value: Push-pull outputs drive USB PD controller GPIOs directly without pull-up resistors, reducing system power by 12µA per active line. |
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 |
|---|---|---|---|
| LMV393QDR | Higher 25µA supply current; open-drain outputs require external pull-ups; no internal hysteresis. | Suitable for cost-sensitive automotive modules where external hysteresis and pull-ups are acceptable. | Select if design already uses pull-up networks and requires AEC-Q100 qualification. |
| TLV3702IDR | Lower 1.8µA supply current but 3.5µs propagation delay; rail-to-rail input only (not output); SO-8 package. | Better for ultra-low-power wake-up circuits where speed is secondary to microamp-level sleep current. | Select when battery life >10 years is required and response time <10µs is sufficient. |
Compared with LMV393QDR and TLV3702IDR, the AZV3002S-13 uniquely balances ultra-low 9µA consumption, 0.8µs speed, push-pull outputs, and built-in hysteresis - making it optimal for space-constrained, dual-threshold portable electronics where BOM reduction and noise immunity are critical.

FAQ
Does AZV3002S-13 support operation below 1.6V?
No. The absolute minimum supply voltage is 1.6V as specified in Absolute Maximum Ratings and DC Electrical Characteristics. Operation below this voltage is not guaranteed and may result in undefined output states or increased propagation delay. The device is characterized and tested from 1.6V to 5.5V, with stable performance across that full range.
Can AZV3002S-13 drive an LED directly?
Yes - its push-pull output can source up to 5mA and sink up to 5mA at 5.5V supply, enabling direct connection of standard 2mA LEDs (with series resistor). At lower supplies (e.g., 1.8V), output voltage swing remains rail-to-rail, but sourced current drops to ~0.5mA; verify LED forward voltage and desired brightness before implementation.
Is external hysteresis required when using AZV3002S-13?
No - the device includes 9mV typical internal hysteresis, sufficient for most noise-prone applications like battery monitoring or sensor threshold detection. External hysteresis is only needed when greater noise margin (>15mV) or asymmetric trip points are required, implemented via positive feedback from OUT to IN+ or IN−.
What is the thermal resistance (θJA) of the SO-8 package?
The SO-8 variant (AZV3002S-13) has a junction-to-ambient thermal resistance of 220°C/W under standard JEDEC 2-layer board conditions. This value assumes 1 in² copper pad area per side; actual θJA improves with enhanced PCB copper pour or thermal vias, supporting continuous operation up to +85°C ambient with ≤15mW total dissipation.
