概述

Description

LMV331M5X/NOPB is TI’s single‑channel, low‑power voltage comparator from the LMV331 family. It compares two input voltages and outputs a digital level indicating which input is higher. Designed for battery-powered, low‑voltage systems, it typically operates on a single supply in the 2.7–5.5 V range with low quiescent current and a rail‑to‑rail output/input range (including ground, depending on variant). The M5X suffix indicates the 8‑pin M5X package, and NOPB denotes Pb‑free packaging. Common uses include threshold detection, zero‑cross sensing, battery and power‑supply monitoring, and other simple comparator‑based controls. For exact electrical specs, package details, and the specific output type (open‑drain or push‑pull) for your variant, consult the TI datasheet.

Features

Here are the typical features of TI LMV331M5X/NOPB (MSOP-8, Pb-free):
- Single-supply operation: 2.7 V to 5.5 V
- Very low quiescent current (micro-power operation)
- Input common-mode range includes ground
- Open-collector or push-pull output suitable for logic levels (TTL/CMOS-compatible)
- Fast response/propagation delay for high-speed sensing
- Industrial temperature range: -40°C to 125°C
- 8-pin MSOP package (M5X), RoHS-compliant, NOPB
- Robust ESD protection and fault tolerance on inputs
- Utility across sensor, level-shifting, and window-detection applications

Package

MSOP-8 (8-pin MSOP package), lead-free (NOPB).

Pinout

- Pin count: 8 pins (MSOP-8 package, suffix M5X, NOPB)
- Function: Single-channel voltage comparator. Compares non-inverting (+IN) and inverting (-IN) inputs and outputs a digital signal (with VCC and GND power pins; other pins may be NC).

Manufacturer

- Manufacturer: Texas Instruments Incorporated (TI).
- What kind of company: American multinational semiconductor company that designs and manufactures analog and embedded processing ICs and other electronics components.

Application

LMV331M5X/NOPB is a low-power, single-supply voltage comparator. Common application areas include:
- Battery-powered portable devices: voltage monitoring, undervoltage/overvoltage detection, hysteresis/window comparators
- Power-management circuits: regulator feedback, PWM/drive comparators, overcurrent/short-circuit protection
- Sensor interfaces: threshold detection for light, temperature, pressure sensors; alarm/window detection
- Signal conditioning: zero-cross and level detection for AC or motor-control signals
- Microcontroller watchdogs and simple alarm/trip circuitry

Equivalent

Direct TI equivalents: TLV331 and LMV331 (same family). Other vendors offer similar single‑supply comparators, but pinouts and specs may differ (e.g., ST TS331, Onsemi NCV331). Always verify with the datasheets or TI cross‑reference/distributor cross‑ref.
