LMV331M5X/NOPB – TI Single Low-Voltage General-Purpose Comparator

LMV331M5X/NOPB is a Texas Instruments single low-voltage comparator designed for compact threshold detection, level sensing and signal comparison circuits. With a 2.7V to 5.5V supply range, open-collector output, low operating current and small 5-pin SOT-23 package, it is suitable for battery-powered equipment, portable electronics, sensor threshold detection, voltage monitoring and general-purpose logic interface circuits.

FunctionSingle Comparator

Supply Range2.7V – 5.5V

OutputOpen Collector

PackageDBV / SOT-23-5

Engineering note: Verify the latest TI datasheet, pull-up resistor value, input common-mode range, output logic level, propagation delay and PCB layout before production approval.

Component Overview

LMV331M5X/NOPB belongs to the TI LMV331-N family of single low-voltage general-purpose comparators. It compares two input voltages and changes its output state according to the input relationship, allowing designers to implement voltage threshold detection, sensor signal decisions and simple control logic.

TomatoElec view: LMV331M5X/NOPB is useful when a design needs a small, economical and low-voltage comparator rather than an operational amplifier. Its value comes from single-comparator integration, 2.7V low-voltage operation, open-collector output flexibility and compact SOT-23-5 packaging.

Circuit Function & Design Role

Threshold Detection

Compares an input signal against a reference voltage to detect overvoltage, undervoltage or signal-level changes.

Sensor Decision Output

Converts analog sensor levels into simple logic-level decisions for MCU or control circuits.

Open-Collector Interface

Allows flexible pull-up voltage selection and wired-OR style logic when used with a proper external pull-up resistor.

Low-Voltage Systems

Supports compact 3V and 5V electronics where low power and small PCB area are important.

Key Electrical & Package Information

Manufacturer	Texas Instruments

Design reminder: Open-collector comparator outputs require a pull-up resistor. The pull-up voltage, resistor value, output sink current and response speed should be checked against the target logic circuit.

Application Scenarios

Voltage Monitoring

Used to detect undervoltage, overvoltage and power-good threshold conditions in low-voltage systems.

Battery-Powered Devices

Suitable for portable electronics and battery systems requiring compact threshold detection.

Sensor Interfaces

Compares analog sensor signals with reference levels for simple on/off or fault decisions.

Logic-Level Interface

Open-collector output helps interface with different logic pull-up voltages when properly designed.

TomatoElec Quality & Supply Notes

As an in-stock independent distributor and electronic components supplier, TomatoElec supports LMV331M5X/NOPB sourcing for engineering samples, production replenishment, urgent replacement and BOM purchasing. For comparator ICs, correct package, manufacturer marking, reel condition and original sourcing are important because the device affects threshold accuracy, output logic behavior and system protection reliability.

Original component sourcing: support sourcing of original Texas Instruments comparator ICs.
Inventory support: help confirm available stock, package condition, date code and shipment schedule.
Package verification: confirm the DBV / SOT-23-5 package and tape-and-reel carrier before shipment.
BOM matching: verify supply range, output type, package, pinout, temperature range and threshold requirements before approving any substitute.

Replacement & BOM Matching Guidance

LMV331M5X/NOPB should not be replaced only by matching the single comparator category. Engineers should compare supply voltage, input common-mode range, input offset voltage, output type, pull-up requirements, propagation delay, package, pinout and operating temperature range.

Selection tip: If the design depends on an open-collector output, replacing it with a push-pull comparator may change logic behavior, pull-up voltage compatibility and fault-line sharing.

FAQ

What is LMV331M5X/NOPB used for?

It is used for voltage threshold detection, sensor signal comparison, low-voltage monitoring, battery-powered devices and logic-level interface circuits.

Is LMV331M5X/NOPB an op amp?

No. LMV331M5X/NOPB is a comparator, not an operational amplifier. It is intended to compare two voltages and switch its output state.

Does LMV331M5X/NOPB need a pull-up resistor?

Yes. Its open-collector output requires an external pull-up resistor selected according to the output voltage, sink current and required response speed.

Can TomatoElec support LMV331M5X/NOPB sourcing?

TomatoElec can support LMV331M5X/NOPB inquiry, inventory confirmation, BOM sourcing and shipment coordination.

Final Selection Summary

LMV331M5X/NOPB is a compact single low-voltage comparator for designs requiring threshold detection, open-collector output flexibility, low-power operation and SOT-23-5 packaging.

TomatoElec recommendation: Use LMV331M5X/NOPB when the BOM requires Texas Instruments single comparator performance, 2.7V to 5.5V operation, open-collector output and DBV / SOT-23-5 packaging.
