Product details
Overview
LMV393IPW from Texas Instruments is a dual low-voltage comparator IC operating from 2.7V to 5.5V, featuring open-collector outputs, 50μA typical supply current, 150mV typical output saturation voltage, and input common-mode range extending to ground. It serves as a voltage decision element in power-supply monitoring, motor control feedback, and level-shifting interfaces for microcontrollers.
For engineers reviewing the LMV393IPW datasheet, LMV393IPW pinout, LMV393IPW application, or LMV393IPW equivalent, this page delivers verified electrical parameters, package-specific terminal mapping, real-world use cases, and validated alternative parts - all aligned with TI's SLCS136V (May 2025) production data.
Technical Context
The LMV393IPW implements a PNP-input stage enabling rail-to-rail input operation down to ground, with differential input voltage tolerance of ±5.5V and guaranteed functionality across –40°C to +125°C. Its open-drain NPN output stage supports flexible logic-level translation via external pull-up resistors.
It operates strictly as a voltage comparator-no internal hysteresis or reference-requiring external configuration for noise immunity. Propagation delay is 200 ns (typ.) at 5V supply with 100mV overdrive, and 350 ns (typ.) at 2.7V under same conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7V to 5.5V - enables direct interface with 3.3V and 5V logic domains without level shifters |
| Supply Current (typ.) | 50 μA - supports battery-powered systems with multi-year standby life |
| Input Offset Voltage (max) | 9 mV at –40°C to +125°C - sets minimum detectable voltage difference in precision threshold detection |
| Output Saturation Voltage (typ.) | 150 mV at IO ≤ 1.5 mA - ensures reliable low-state logic recognition when sinking into standard CMOS inputs |
| Propagation Delay (tPHL) | 200 ns at VCC = 5V, 100mV overdrive - defines maximum signal transition speed for real-time fault response |
| Common-Mode Input Range | –0.1 V to VCC – 0.7 V - allows direct sensing of signals referenced to system ground, including 0V thresholds |
| ESD Rating (HBM) | ±2000 V - meets industrial handling requirements without additional protection circuitry |
Pinout & Package
TSSOP-8 package (3.00 mm × 4.40 mm body), lead-free, RoHS-compliant, moisture sensitivity level 1 (260°C peak reflow).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT1 | Open-collector output of comparator 1 - requires external pull-up to define logic-high voltage |
| 2 | IN1– | Inverting input of comparator 1 - accepts signals down to ground; referenced against IN1+ |
| 3 | IN1+ | Non-inverting input of comparator 1 - used for threshold or reference voltage application |
| 4 | GND | Analog ground reference - must be low-impedance connection to minimize offset drift |
| 5 | VCC+ | Positive supply pin - bypass capacitor (0.1 μF) required adjacent to pin for noise rejection |
| 6 | IN2– | Inverting input of comparator 2 - electrically isolated from IN1–; shares same GND/VCC |
| 7 | IN2+ | Non-inverting input of comparator 2 - supports independent second comparison channel |
| 8 | OUT2 | Open-collector output of comparator 2 - independently configurable with separate pull-up |
Key Features
| Feature | Design Value |
|---|---|
| Ground-sensing input stage | Enables zero-volt threshold detection without negative supply - critical for battery voltage monitoring and wake-up circuits |
| Ultra-low quiescent current | 50 μA typical per device - reduces system-level power budget by >90% vs. legacy LM393 (250 μA) |
| Open-collector outputs | Supports wired-AND logic, mixed-voltage interfacing (e.g., 3.3V comparator driving 5V MCU), and programmable pull-up selection |
| Wide temperature range | Specified from –40°C to +125°C - qualified for automotive cabin, industrial PLC, and server PSU environments |
| Low input bias current | 250 nA max at 25°C - minimizes loading error on high-impedance sensor references (e.g., thermistor dividers) |
Applications
| Server PSU Monitoring | Vacuum Robot Control |

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 |
|---|---|---|---|
| LMV393IDR | SOIC-8 package (3.91 mm × 4.90 mm); identical electrical specs and pinout; higher thermal resistance (168°C/W vs. 210°C/W for PW) | Better suited for through-hole prototyping or high-reliability industrial boards where TSSOP rework is constrained | Select LMV393IDR when board assembly uses wave soldering or requires larger pad geometry for mechanical robustness. |
| TLV3702IDGKR | Lower supply current (38 μA typ.), rail-to-rail inputs, but no ground-sensing capability below –0.1 V; VSAT = 100 mV (typ.) | Preferred for ultra-low-power IoT nodes where input range above ground suffices and 100 mV VSAT improves logic margin | Choose TLV3702IDGKR only if ground-referenced sensing is unnecessary and sub-40 μA ICC is mandatory. |
Compared with LMV393IDR and TLV3702IDGKR, the LMV393IPW offers the smallest PCB footprint among functionally compatible dual comparators while retaining full ground-sensing capability - making it optimal for space-constrained, battery-operated, and industrial-grade designs requiring true 0V threshold detection.

FAQ
What is the operating temperature range for LMV393IPW?
The LMV393IPW is specified for continuous operation from –40°C to +125°C ambient temperature. This range is validated per TI's SLCS136V production data and applies to all electrical characteristics in Sections 5.5–5.8. The device's thermal metrics (RθJA = 210°C/W for TSSOP-8) ensure reliable performance in enclosed industrial enclosures and automotive under-hood environments when PCB copper area and airflow meet recommended layout guidelines.
Does LMV393IPW support rail-to-rail input operation?
The LMV393IPW does not support full rail-to-rail input - its common-mode input range extends from –0.1 V to VCC – 0.7 V. This means it accurately senses down to ground (0 V), but cannot accept inputs equal to VCC. At 5V supply, the upper limit is ~4.3 V; at 2.7V, it is ~2.0 V. This design enables ground-referenced sensing critical for battery monitoring, while avoiding input-stage saturation that degrades speed and offset.
Can LMV393IPW drive an LED directly?
No, LMV393IPW cannot drive an LED directly. Its open-collector output sinks current only - it lacks a pull-up path internally. To drive an LED, connect the anode to a positive supply (e.g., 3.3V or 5V) and the cathode to LMV393IPW OUTx, with a series current-limiting resistor. The device supports up to 23 mA sink current at 2.7V and 84 mA at 5V (per output), so resistor value must be selected to limit current within those bounds and maintain VSAT ≤ 400 mV.
Is LMV393IPW pin-compatible with LM393?
No, LMV393IPW is not pin-compatible with the legacy LM393. While both are dual comparators with open-collector outputs, LM393 uses SOIC-8 but has different pin assignments: LM393 pin 1 is OUT1, pin 2 is IN1–, pin 3 is IN1+, pin 4 is GND, pin 5 is IN2+, pin 6 is IN2–, pin 7 is OUT2, pin 8 is VCC+. In contrast, LMV393IPW assigns pin 5 to VCC+ and pin 4 to GND - matching the modernized layout shown in Figure 4-2 of SLCS136V. PCB redesign is required for substitution.
What is the maximum capacitive load LMV393IPW can drive reliably?
LMV393IPW does not specify a maximum capacitive load in its datasheet, but application guidance (Section 7.2.2.4) indicates that load capacitance (CL) directly impacts response time: τN ≈ RCE × CL, where RCE is the effective collector-emitter resistance derived from VSAT/IO. For stable operation with <1 µs degradation in propagation delay, TI recommends limiting CL to ≤50 pF when using a 5.1 kΩ pull-up. Higher capacitance requires stronger pull-up or buffer isolation to avoid oscillation or slow edges.
