Product details
Overview
LMV393S-13 from Diodes Incorporated is a dual low-voltage comparator IC operating from 2.7V to 5.5V supply, featuring open-collector outputs, 40 µA/comparator typical supply current at 2.7V, −40°C to +125°C operating temperature range, and input common-mode range extending to ground-designed for battery-powered portable electronics requiring space- and power-constrained signal threshold detection.
For engineers reviewing the LMV393S-13 datasheet, LMV393S-13 pinout, LMV393S-13 application, or LMV393S-13 equivalent, key selection criteria include dual-channel open-collector output flexibility, guaranteed 2.7V operation, rail-to-rail input capability down to ground, low quiescent current across temperature, and SOP-8 package compatibility with standard PCB assembly processes.
Technical Context
The LMV393S-13 implements two independent voltage comparators using BiCMOS process technology, combining bipolar input stages for low noise and CMOS output stages for low power. Each channel features an open-collector output requiring external pull-up, enabling wired-OR logic and level translation across different supply domains.
Its input stage supports common-mode voltages from −0.1 V (below VEE) to +4.2 V (at 5 V supply), and propagation delays are specified at 200 ns (tPHL) and 300 ns (tPLH) under 100 mV overdrive at 5 V - optimized for fast response in low-voltage sensing without sacrificing stability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 5.5 V - enables direct integration into single-cell Li-ion (3.0–3.7 V) and USB-powered (5 V) systems without regulation. |
| Supply Current (Typ) | 70 µA (both comparators at 2.7 V) - supports multi-year battery life in always-on monitoring circuits. |
| Input Offset Voltage (Max) | 7 mV at 2.7 V - ensures reliable threshold detection with ≤1% error for 700 mV reference signals. |
| Propagation Delay (tPHL) | 200 ns at 5 V, 100 mV overdrive - suitable for sub-5 MHz window-compare timing in power sequencing or fault detection. |
| Output Type | Open-collector - allows flexible pull-up to higher or lower voltage rails, supporting mixed-supply interface and wired-OR bus configurations. |
| Input Common-Mode Range | −0.1 V to +4.2 V at 5 V supply - accommodates ground-referenced sensors and rail-sensing applications without level-shifting. |
| Operating Temperature | −40°C to +125°C - qualified for automotive cabin, industrial control, and extended-range portable equipment environments. |
Pinout & Package
SOP-8 package (standard SOIC-8 footprint, 1.27 mm pitch), surface-mount, RoHS-compliant, halogen-free "Green" molding compound.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (1OUT) | Comparator 1 Output | Open-collector drain - requires external pull-up; sinks up to 23 mA at 2.7 V for driving LEDs or logic inputs. |
| 2 (1IN−) | Comparator 1 Inverting Input | Differential input node - accepts analog signals down to −0.1 V relative to VEE (GND). |
| 3 (1IN+) | Comparator 1 Non-inverting Input | Differential input node - used for threshold comparison against reference or sensor voltage. |
| 4 (VEE) | Negative Supply / Ground | Reference return path - tied to system GND in single-supply operation; supports true ground-sensing. |
| 5 (2IN+) | Comparator 2 Non-inverting Input | Independent second channel input - enables dual-threshold or window-compare functionality. |
| 6 (2IN−) | Comparator 2 Inverting Input | Independent second channel input - configurable for hysteresis or differential sensing. |
| 7 (2OUT) | Comparator 2 Output | Open-collector drain - electrically isolated from Channel 1; supports independent load switching. |
| 8 (VCC) | Positive Supply | Primary power rail - supplies both comparators; bypass capacitor (≥0.1 µF) required adjacent to this pin. |
Key Features
| Feature | Design Value |
|---|---|
| Guaranteed 2.7 V operation | Validated performance at minimum supply - eliminates need for LDO pre-regulation in coin-cell or single-LiFePO₄ systems. |
| Input common-mode to ground | Enables direct connection of 0 V–reference sensors (e.g., thermistors, current-sense amps) without offset biasing. |
| 40 µA/comparator supply current | Reduces total standby power to <150 µA for dual-channel monitoring - critical for IoT endpoint wake-on-event designs. |
| Open-collector outputs | Permits level translation between 1.8 V logic and 5 V peripherals, and supports shared interrupt buses with multiple sources. |
| −40°C to +125°C operation | Qualified across full industrial/automotive ambient range - no derating required for under-hood or outdoor enclosure use. |
Applications
| Power Sequencing Monitor | Battery Voltage Supervisor |
|---|---|

| USB-C Port Protection | Industrial Sensor Threshold Alarm |
|
Use Scenario: Validating VBUS presence and overvoltage in USB-C receptacle circuits before enabling downstream power switches.

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 |
|---|---|---|---|
| LM393DR (TI) | Higher supply current (500 µA typ), wider supply range (2–36 V), no guaranteed 2.7 V operation. | Requires external regulator for 2.7 V systems; unsuitable for ultra-low-power battery operation. | Select only when wide supply range or legacy pinout compatibility outweighs power savings. |
| TLV3702IDR (TI) | Push-pull output, rail-to-rail input, 85 µA supply current, 1.8–5.5 V supply. | No external pull-up needed; incompatible with wired-OR or level-shifted bus topologies. | Prefer when driving CMOS loads directly or minimizing BOM count; avoid if open-collector flexibility is required. |
Compared with LM393DR and TLV3702IDR, the LMV393S-13 uniquely balances ultra-low quiescent current, guaranteed 2.7 V operation, and open-collector output - making it optimal for space-constrained, battery-sensitive dual-threshold detection where bus sharing or mixed-voltage interfacing is essential.

FAQ
Does LMV393S-13 require external pull-up resistors on its outputs?
Yes - both outputs are open-collector and must be pulled up externally. Diodes Incorporated recommends 1 kΩ to 10 kΩ resistors depending on sink current and rise-time requirements. At 5 V supply and 10 kΩ pull-up, the output rises in <100 ns with 10 pF load, per typical application data.
Can LMV393S-13 operate with a single 3.3 V supply?
Yes - it is fully specified from 2.7 V to 5.5 V. At 3.3 V, supply current is typically 85 µA (both channels), input offset voltage remains ≤7 mV, and propagation delay improves to ~250 ns (tPHL) with 100 mV overdrive, making it ideal for 3.3 V microcontroller peripheral interfacing.
What is the maximum sink current per output of LMV393S-13?
Each output can sink up to 23 mA at 2.7 V and 84 mA at 5 V (VO ≤ 1.5 V), per electrical characteristics table. This supports direct LED driving, relay coil control (with flyback diode), or TTL/CMOS logic level translation without additional drivers.
Is LMV393S-13 pin-compatible with standard LM393 SO-8 packages?
Yes - pin assignments match industry-standard LM393 SO-8 layout: Pin 1 = OUT1, Pin 2 = IN1−, Pin 3 = IN1+, Pin 4 = GND, Pin 5 = IN2+, Pin 6 = IN2−, Pin 7 = OUT2, Pin 8 = VCC. No PCB redesign is needed for drop-in replacement in existing LM393 footprints.
