Product details
Overview
AZV393MMTR-G1 from Diodes Incorporated is a dual general-purpose low-voltage comparator operating from 2.5V to 5.5V supply, featuring 100µA typical supply current, open-collector outputs, and input common-mode range extending to ground - optimized for battery-powered portable electronics including notebooks, PDAs, and mobile communications devices.
For engineers reviewing the AZV393MMTR-G1 datasheet, AZV393MMTR-G1 pinout, AZV393MMTR-G1 application, or AZV393MMTR-G1 equivalent, key selection criteria include supply current vs. voltage dependency, propagation delay under 100mV overdrive (200–600 ns), output saturation voltage ≤200mV at 1–4mA sink, and compatibility with SOIC-8/TSSOP-8/MSOP-8 footprints.
Technical Context
The AZV393 employs a BiCMOS process with bipolar input and output stages to achieve low noise, rail-to-rail input capability down to ground, and robust performance across -40°C to +85°C ambient temperature. Its open-collector outputs support wired-OR logic and flexible pull-up configurations up to 6V.
It delivers guaranteed operation across 2.5V–5.5V supply, with input offset voltage ≤7mV (typ. 1.7mV), input bias current ≤250nA, and propagation delays specified at both 10mV and 100mV input overdrive - enabling precise timing in low-power threshold detection and oscillator circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.5V to 5.5V - supports single-cell Li-ion, two-cell alkaline, and regulated 3.3V/5V rails without level-shifting. |
| Supply Current (Typ.) | 100µA at 2.7V - enables multi-year operation in coin-cell–powered sensors and wearables. |
| Input Offset Voltage | 1.7mV (typ.), 7mV (max) - ensures accurate voltage thresholding in battery monitoring and power-good detection. |
| Output Saturation Voltage | 200mV (typ.) at 1mA sink - minimizes voltage drop in active-low interrupt signaling to microcontrollers. |
| Propagation Delay | 200ns (TPLH/TPHL, 100mV overdrive, VCC=5V) - suitable for kHz-range oscillators and fast response window comparators. |
| Input Common-Mode Range | -0.1V to VCC–1.2V - includes ground reference, enabling direct sensing of 0V-referenced signals like battery negative terminals. |
| Operating Temperature | -40°C to +85°C - qualified for industrial and consumer portable equipment environments. |
Pinout & Package
AZV393MMTR-G1 is packaged in MSOP-8 (3.0mm × 3.0mm, 0.65mm pitch), a space-constrained footprint ideal for ultra-thin portable designs. The device uses standard dual-comparator pinout compatible with LMV393.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUTPUT 1 | Open-collector output - requires external pull-up; sinks current when IN1+ > IN1−. |
| 2 | IN1− | Inverting input of Comparator 1 - accepts analog signals within VEE to VCC–1.2V. |
| 3 | IN1+ | Non-inverting input of Comparator 1 - referenced to ground or adjustable threshold voltage. |
| 4 | VEE | Ground terminal - tied to system GND; enables true ground-sensing capability. |
| 5 | IN2+ | Non-inverting input of Comparator 2 - independent channel for dual-threshold or hysteresis configuration. |
| 6 | IN2− | Inverting input of Comparator 2 - supports differential or single-ended signal comparison. |
| 7 | OUTPUT 2 | Open-collector output - electrically isolated from OUTPUT 1; enables independent control paths. |
| 8 | VCC | Positive supply rail - powers both comparators and internal bias circuitry; tolerant to 6V absolute max. |
Key Features
| Feature | Design Value |
|---|---|
| BiCMOS Process Architecture | Combines bipolar input stage (low noise, precision) with CMOS output drive (low quiescent current, high speed). |
| Ground-Sensing Input Range | Input common-mode extends to −0.1V, allowing direct interface with 0V-referenced battery or sensor outputs. |
| Low-Voltage Compatibility | Guaranteed operation down to 2.5V supply - eliminates need for voltage boosters in single-cell systems. |
| Pin-for-Pin LMV393 Replacement | Drop-in upgrade path with identical pinout and improved supply current (100µA vs. LMV393's 160µA typ.). |
| Green, Lead-Free Packaging | G1 suffix denotes halogen-free, RoHS-compliant MSOP-8 package with matte tin lead finish. |
Applications
| Notebook Power Management | Portable Medical Sensor Interface |
|---|---|
|
Use Scenario: Monitoring battery voltage thresholds and system reset conditions in ultraportable laptops and 2-in-1 tablets. IC Role / Device Role / Timing Role: Dual comparator performs simultaneous low-battery warning (OUT1) and power-good validation (OUT2) with independent hysteresis. Use Value: 100µA supply current extends standby time; ground-sensing inputs directly monitor cell voltage without level shifters. |
Use Scenario: Detecting physiological signal thresholds (e.g., ECG R-wave peaks or pulse oximetry saturation levels) in wearable health monitors. IC Role / Device Role / Timing Role: Comparator 1 triggers wake-up on signal amplitude crossing; Comparator 2 validates signal integrity via window detection. Use Value: 200ns propagation delay enables sub-millisecond response; open-collector outputs interface directly with low-voltage MCU GPIOs. |
| Mobile Phone Charger Detection | Smart Home Battery Backup System |
|
Use Scenario: Identifying USB charger type (SDP/CDP/DCP) by comparing D+/D− line voltages during enumeration. IC Role / Device Role / Timing Role: Dual comparator compares differential USB data lines against reference voltages to classify charger signature patterns. Use Value: 7mV max input offset ensures reliable classification across temperature; 5.5V VCC tolerance supports legacy 5V USB ports. |
Use Scenario: Managing seamless switchover between mains power and backup LiFePO₄ battery in smart thermostats and security hubs. IC Role / Device Role / Timing Role: One comparator monitors AC presence; the other tracks battery SOC via shunt voltage, triggering relay control logic. Use Value: Industrial temperature rating (-40°C to +85°C) ensures reliability in unconditioned enclosures; MSOP-8 saves PCB area in compact modules. |
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 |
|---|---|---|---|
| LMV393DR | Higher 160µA typical supply current; same SOIC-8 pinout; no MSOP-8 option. | Lacks MSOP-8 footprint - unsuitable for space-constrained designs requiring <3mm × 3mm packages. | Select when legacy SOIC-8 layout reuse is prioritized over ultra-low power or miniaturization. |
| TLV3702IDR | Lower 80µA supply current; rail-to-rail input/output; but 1.8V–5.5V supply range and higher 1.5mV offset drift. | Supports 1.8V systems (e.g., BLE SoCs); however, higher TCVOS reduces long-term accuracy in wide-temp environments. | Prefer for sub-2.5V operation or rail-to-rail output swing needs - not for ground-sensing precision at 2.5V. |
Compared with LMV393DR and TLV3702IDR, AZV393MMTR-G1 uniquely balances ultra-low quiescent current (100µA), ground-sensing input, MSOP-8 packaging, and proven stability across -40°C to +85°C - making it optimal for next-gen portable electronics where size, battery life, and precision coexist.

FAQ
Can AZV393MMTR-G1 operate with a 2.5V supply while maintaining full functionality?
Yes. The AZV393MMTR-G1 is fully specified from 2.5V to 5.5V per its Recommended Operating Conditions. At 2.5V, it delivers 100µA typical supply current, 7mV max input offset voltage, and functional open-collector outputs with 500mV max saturation voltage at 1mA sink - meeting all key parameters without derating.
Does AZV393MMTR-G1 require external hysteresis resistors for stable switching?
No. While hysteresis is not internally integrated, the device supports external positive feedback via standard resistor networks on either input. Its low input bias current (≤250nA) and 1.7mV typical offset enable predictable hysteresis design - commonly implemented using 1MΩ–10MΩ feedback resistors without compromising accuracy.
Is the MSOP-8 package of AZV393MMTR-G1 compatible with standard reflow profiles?
Yes. The AZV393MMTR-G1 (G1 suffix) uses a green, lead-free matte tin finish and conforms to IPC/JEDEC J-STD-020D moisture sensitivity level 1 (MSL-1). It supports standard Pb-free reflow profiles with peak temperatures up to 260°C for 10 seconds, verified per Diodes' package reliability testing.
How does AZV393MMTR-G1 handle input signals below ground?
The AZV393MMTR-G1 specifies an input common-mode range down to −0.1V relative to VEE (GND). Inputs below ground are not supported and may cause phase reversal or latch-up. For sub-ground sensing, external clamping diodes or level-shifting circuitry must be added - the device itself is not designed for negative input voltages.
