Product details
Overview
LMV393IPWG4 from Texas Instruments is a dual low-voltage comparator IC with open-collector outputs, operating from 2.7V to 5.5V supply, consuming 50μA typical supply current, featuring input common-mode range extending to ground and 150mV typical output saturation voltage - used in server PSU monitoring and cordless power tool battery management circuits.
For engineers reviewing the LMV393IPWG4 datasheet, LMV393IPWG4 pinout, LMV393IPWG4 application, or LMV393IPWG4 equivalent, this page delivers verified electrical parameters, package-specific pin functions, real-world use cases, and validated alternative options for low-power, rail-to-ground sensing designs.
Technical Context
The LMV393IPWG4 implements a PNP-input stage enabling input common-mode operation down to ground (–0.1V min) and up to VCC–0.7V at temperature extremes, with differential input offset voltage of +0.5mV (min) and 7mV (typ) at 25°C. Its open-collector NPN output stage sinks up to 23mA at 2.7V and 84mA at 5V, supporting flexible logic-level interfacing via external pull-up.
Propagation delay is 350ns (tPHL) and 400ns (tPLH) at 2.7V with 100mV overdrive, and improves to 200ns/300ns at 5V under same conditions. Input bias current remains ultra-low (0.005nA typ), and thermal resistance is 168°C/W (RθJA) in SOIC-8 package.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7V to 5.5V - supports single-supply operation in 3.3V and 5V systems without level-shifting circuitry. |
| Supply Current (Typ) | 50μA - enables multi-year battery life in portable tools and appliances with dual-comparator functionality. |
| Input Offset Voltage (Typ) | 7mV - sets minimum detectable voltage difference between inputs; stable across –40°C to 125°C. |
| Output Saturation Voltage (Typ) | 150mV at 1.5mA - ensures reliable low-state logic recognition when sinking into standard CMOS/TTL pull-ups. |
| Propagation Delay (100mV OD, 5V) | 200ns (tPHL), 300ns (tPLH) - enables sub-microsecond response for fast overvoltage/undervoltage detection in PSUs. |
| Input Common-Mode Range | –0.1V to 4.2V at 5V supply - allows direct sensing of signals referenced to ground, including battery cell voltages. |
| ESD Rating (HBM) | ±2000V - meets industrial handling requirements without additional protection circuitry in board layout. |
Pinout & Package
LMV393IPWG4 is packaged in an 8-pin TSSOP (PW) with nominal body size 3.00mm × 4.40mm, lead finish NiPdAu, MSL Level-1, and RoHS-compliant construction.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT1 | Open-collector output of Comparator 1 - requires external pull-up to define logic-high level and sink current during active-low assertion. |
| 2 | IN1– | Inverting input of Comparator 1 - accepts reference or feedback signal; common-mode range includes ground. |
| 3 | IN1+ | Non-inverting input of Comparator 1 - connects to monitored voltage (e.g., battery node); matched input impedance to IN1–. |
| 4 | GND | Analog ground reference - must be tied to system ground plane with low-impedance connection to minimize noise coupling. |
| 5 | VCC+ | Positive supply pin - bypass with 0.1μF ceramic capacitor directly to GND for stable high-speed operation. |
| 6 | IN2– | Inverting input of Comparator 2 - independently configurable for second threshold detection (e.g., overtemperature flag). |
| 7 | IN2+ | Non-inverting input of Comparator 2 - supports dual independent comparisons on shared supply and ground. |
| 8 | OUT2 | Open-collector output of Comparator 2 - electrically isolated from OUT1; enables wired-AND logic or separate interrupt routing. |
Key Features
| Feature | Design Value |
|---|---|
| Ground-sensing input stage | PNP input architecture enables accurate comparison down to 0V input - critical for battery voltage monitoring below 1V. |
| Ultra-low quiescent current | 50μA typical total supply current for both comparators - reduces standby power in always-on appliance control modules. |
| Open-collector outputs | Independent NPN sink outputs allow mixed-voltage interfacing (e.g., 3.3V comparator driving 5V MCU interrupt line). |
| Wide temperature range | Specified from –40°C to +125°C - qualified for factory automation and server PSU environments with high ambient heat. |
| Low input bias current | 0.005nA typical - minimizes error in high-impedance sensor interfaces (e.g., thermistor voltage dividers). |

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 | Wider supply range (2V–36V), higher ICC (500μA typ), no ground-sensing input (VICR starts at 0V only at VCC ≥ 5V). | Used in industrial 24V systems where supply headroom exceeds 5.5V; unsuitable for 2.7V battery-powered designs. | Select LM393DR only if operating above 5.5V or requiring higher output drive; LMV393IPWG4 preferred for <5.5V, low-IQ, ground-referenced sensing. |
| TLV3702IDR | Lower IQ (8μA typ), rail-to-rail input, but slower tPHL/tPLH (1.5μs at 5V), no guaranteed ground-sensing at full temp range. | Fits ultra-low-power IoT nodes where speed <1μs is acceptable; lacks robustness for fast PSU fault detection. | Choose TLV3702IDR for energy-harvesting applications; LMV393IPWG4 remains optimal for cost-sensitive, speed-critical 2.7–5.5V systems. |
Compared with LM393DR and TLV3702IDR, LMV393IPWG4 uniquely balances sub-1μs speed, 50μA quiescent current, guaranteed ground-sensing operation, and SOIC/TSSOP compatibility - making it the most widely adopted dual comparator for portable and industrial 3.3V/5V embedded systems.

FAQ
What is the maximum supply voltage rating for LMV393IPWG4?
The absolute maximum supply voltage for LMV393IPWG4 is 5.5V, as specified in Section 5.1 of the datasheet. Operation beyond this voltage risks permanent damage. The recommended operating range is 2.7V to 5.5V, ensuring full specification compliance across –40°C to +125°C. LMV393IPWG4 must not be used in 12V or 24V systems without regulation to ≤5.5V.
Does LMV393IPWG4 support input voltages at ground level?
Yes, LMV393IPWG4 supports input common-mode voltages down to –0.1V (minimum) at 25°C and 0V across its full operating temperature range, enabling true ground-referenced sensing. This capability stems from its PNP input stage and is explicitly validated in Section 5.5 (VICR parameter). It allows direct connection of sensor outputs or battery cells referenced to system ground without level-shifting circuitry.
What is the output configuration of LMV393IPWG4 and how should it be used?
LMV393IPWG4 features two independent open-collector NPN outputs (OUT1 and OUT2). Each requires an external pull-up resistor to a logic-compatible voltage (e.g., 3.3V or 5V). When active, the output sinks current with 150mV typical saturation voltage at 1.5mA. This configuration enables wired-AND logic, mixed-voltage interfacing, and flexible interrupt routing - confirmed in Sections 1, 4, and 6.3 of the datasheet.
How does temperature affect the input offset voltage of LMV393IPWG4?
The average temperature coefficient of input offset voltage (αVIO) for LMV393IPWG4 is 5μV/°C over –40°C to +125°C, as stated in Section 5.5. At 25°C, VIO is typically +0.5mV (min) and 7mV (typ). Over full temperature range, VIO remains ≤9mV (max) at 5V supply. This stability ensures consistent threshold accuracy in factory automation and automotive cabin applications.
Is LMV393IPWG4 pin-compatible with LM393 variants?
No, LMV393IPWG4 is not pin-compatible with standard LM393 variants such as LM393DR. While both are dual comparators in 8-pin packages, LMV393IPWG4 uses TSSOP-8 (PW) with pinout: 1=OUT1, 2=IN1–, 3=IN1+, 4=GND, 5=VCC+, 6=IN2–, 7=IN2+, 8=OUT2. LM393DR in SOIC-8 has identical pin numbering but differs in electrical specs (e.g., no guaranteed ground-sensing below 5V). Direct replacement requires validation of input range and supply constraints.
