Product details
Overview
AZV393GTR-G1 from Diodes Incorporated is a dual general-purpose low-voltage comparator operating from 2.5V to 5.5V, featuring 100µA typical supply current, open-collector outputs, and input common-mode range extending to ground-enabling direct sensing of signals referenced to system ground in battery-powered portable electronics.
For engineers reviewing the AZV393GTR-G1 datasheet, AZV393GTR-G1 pinout, AZV393GTR-G1 application, or AZV393GTR-G1 equivalent, this device serves as a pin-for-pin replacement for LMV393 in space-constrained, low-power systems requiring rail-to-rail input capability, low saturation voltage (200mV typ), and industrial temperature operation (–40°C to +85°C).
Technical Context
The AZV393GTR-G1 integrates two independent comparators fabricated using BiCMOS process technology, combining bipolar input stages for low noise and high gain with CMOS output stages for low power consumption. Its open-collector outputs support wired-OR logic and flexible pull-up voltage selection up to 6V.
Input offset voltage is specified at 1.7–7 mV over temperature, with average drift of 5 µV/°C; propagation delays are 200 ns (TPHL) and 300 ns (TPLH) at 5V with 100mV overdrive, supporting reliable timing in oscillator and level-detection circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.5V to 5.5V - supports single-cell Li-ion, 3.3V, and 5V logic rails without level-shifting. |
| Supply Current | 100µA typical - enables multi-year battery life in always-on sensor monitoring nodes. |
| Input Offset Voltage | 1.7–7 mV - ensures accurate threshold detection in precision voltage monitoring applications. |
| Output Saturation Voltage | 200mV typical at 1mA sink - minimizes power loss and improves low-voltage logic compatibility. |

| Propagation Delay | 200 ns (TPHL) / 300 ns (TPLH) at 5V - suitable for kHz-range oscillators and fast response window detectors. |
| Operating Temperature | –40°C to +85°C - qualified for industrial and consumer portable equipment environments. |
Pinout & Package
AZV393GTR-G1 is supplied in green (halogen-free, RoHS-compliant) TSSOP-8 package (4.3mm × 3.0mm, 0.65mm pitch), optimized for high-density PCB layouts in portable devices.
| Pin/Terminal | Circuit Role | Design Meaning |

| 2 | IN1– | Inverting input of Comparator 1 - accepts signals down to –0.1V for ground-referenced differential sensing. |
| 3 | IN1+ | Non-inverting input of Comparator 1 - supports rail-to-rail common-mode range including ground. |
| 4 | GND | Ground reference for both comparators and internal circuitry - shared return path for all analog functions. |
| 5 | IN2+ | Non-inverting input of Comparator 2 - electrically isolated from IN1+; enables dual independent thresholds. |
| 6 | IN2– | Inverting input of Comparator 2 - matched bias current and offset characteristics to IN1±. |
| 7 | OUT2 | Open-collector output of Comparator 2 - independently configurable; supports asynchronous event detection. |
| 8 | VCC | Positive supply rail - powers both comparators; decoupling capacitor recommended within 5mm. |

Applications
| Notebook and PDA Power Monitoring | Mobile Communications Battery Protection |
|---|---|
Use Scenario: Real-time monitoring of Li-ion battery voltage during charge/discharge cycles in ultraportable computing devices. IC Role / Device Role / Timing Role: Dual comparator implements overvoltage and undervoltage lockout with independent thresholds on each channel. Use Value: Prevents system damage by triggering shutdown when cell voltage exceeds 4.3V or drops below 3.0V, using only 100µA quiescent current. | Use Scenario: Detection of RF power amplifier enable/disable states and antenna switch control in 4G/LTE handsets. IC Role / Device Role / Timing Role: Comparator 1 monitors PA bias voltage; Comparator 2 detects antenna tuning voltage thresholds for band switching. Use Value: Enables fast (<300ns) state transitions between transmit/receive modes while consuming negligible standby power. |
| One-Shot Multivibrator Circuit | Low-Power Sensor Wake-Up System |
Use Scenario: Generating precise pulse-width timing signals for LED flash control or motor stall detection in handheld tools. IC Role / Device Role / Timing Role: Configured as an RC-triggered monostable multivibrator using internal hysteresis and open-collector feedback. Use Value: Delivers stable 10–100ms pulses with <5% variation across temperature, eliminating need for external timer ICs. | Use Scenario: Ultra-low-power wake-up trigger for environmental sensors (e.g., motion, light, humidity) in IoT edge nodes. IC Role / Device Role / Timing Role: Comparator monitors analog sensor output against programmable threshold; asserts interrupt on OUT1/OUT2 to MCU. Use Value: Reduces system sleep current to <1µA total by disabling MCU until threshold crossing occurs, extending battery life to >5 years. |
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 |
|---|---|---|---|
| LMV393DR2G | Higher supply current (160µA typ), wider offset range (±7mV), same SOIC-8/TSSOP-8 footprint. | Less suitable for sub-100µA battery-critical designs; better noise immunity at higher frequencies. | Select when higher speed (450ns propagation) or proven qualification history outweighs current savings. |
| TLV393IDR | Lower offset (0.5mV max), rail-to-rail inputs/outputs, but 250µA supply current and no ground-sensing capability. | Requires level-shifting for ground-referenced inputs; preferred in precision analog front-ends over portable power monitoring. | Choose for high-accuracy thresholding where supply current >200µA is acceptable and full rail-to-rail swing is required. |
Compared with LMV393DR2G and TLV393IDR, AZV393GTR-G1 uniquely balances ultra-low quiescent current (100µA), ground-sensing inputs, and open-collector flexibility-making it optimal for cost-sensitive, battery-constrained portable systems where pin compatibility and minimal BOM change are critical.

FAQ
What is the maximum allowable supply voltage for AZV393GTR-G1?
The absolute maximum supply voltage is 6V, but continuous operation above 5.5V risks reliability degradation. The device is characterized and guaranteed for stable operation from 2.5V to 5.5V per datasheet Section 6.1; exceeding 5.5V voids parametric guarantees and may accelerate electromigration in internal traces.
Can AZV393GTR-G1 drive a 5V logic input directly?
Yes - its open-collector outputs support pull-up to any voltage ≤6V, including 5V logic rails. With a 5.1kΩ pull-up to 5V, the output saturates to ≤200mV at 1mA sink, ensuring valid LOW-level recognition by standard TTL and CMOS inputs across temperature.
Does AZV393GTR-G1 require external hysteresis for stable operation?
No internal hysteresis is provided; external positive feedback is required for noise immunity in slow-moving or noisy input signals. Typical hysteresis values range from 10mV to 50mV, implemented via resistor divider from output to non-inverting input - confirmed in Figure 1 of DS36552 Rev. 1-4.
Is the G1 suffix indicative of RoHS compliance and halogen-free construction?
Yes - the G1 suffix explicitly denotes Diodes Incorporated's green packaging: lead-free (Pb-free), halogen-free, and compliant with RoHS Directive 2011/65/EU and JEDEC JS-709B. This is documented in the Ordering Information table on page 9 of DS36552 Rev. 1-4.
