概述

Description

LMV331SN3T1G is a TI single-channel, low-voltage voltage comparator from the LMV33x family. It’s designed for battery-powered, single-supply systems.
Key points
- Input: rail-to-rail (includes ground); output: rail-to-rail swing (logic-friendly)
- Supply: 2.7 V to 5.5 V
- Low quiescent current and fast response
- Package: SOT-23-3 (SN3T1G), RoHS-compliant
Typical uses
- Threshold/level detection, zero-cross detectors, window sensing
- Sensor interfaces and other portable/energy-efficient applications
Notes
- Use proper hysteresis if needed for noisy signals
- Check the datasheet for exact propagation delay, bias currents, output drive, and recommended operating conditions.

Features

Here are the key features of LMV331SN3T1G:
- Single-supply comparator
- Operating supply range: 2.7 V to 5.5 V
- Rail-to-rail input and rail-to-rail output
- Input common-mode range extends to the negative rail (ground)
- Push-pull (totem-pole) output
- Very low input bias current (CMOS)
- Low input offset voltage
- Wide operating temperature: -40°C to 125°C
- Package: SOT-23-3 (LMV331SN3T1G)
Applications include threshold/detection, level shifting, and zero-cross sensing in low-voltage systems.

Package

SC-70-5 (5-pin) small-outline package; RoHS-compliant (lead-free).

Pinout

- Pin count: 5 pins (SC70/SOT-23-5 package variants)
- Function: General-purpose, single-supply voltage comparator with two inputs (non-inverting and inverting), one output, and power (Vcc) and ground (GND) pins. It compares the inputs and outputs a logic level corresponding to which input is higher.

Manufacturer

- Manufacturer: Texas Instruments (TI).
- What kind of company: A US-based multinational technology company and one of the world's largest semiconductor manufacturers, specializing in analog and mixed-signal ICs, embedded processors, and related products.

Application

LMV331SN3T1G is a low‑power, single‑channel voltage comparator. Common applications include:
- Battery-powered monitoring (under/overvoltage, low‑battery indication)
- Zero‑cross and threshold sensing for PWM regulators
- Sensor interfaces (thermistors, photo sensors, current shunt with hysteresis)
- Level shifting and input conditioning for microcontrollers
- Protection/alarm circuits (LED drivers, watchdogs)
Suitable for portable electronics, DC/DC converters, and automotive/industrial sensing where low power is required.

Equivalent

Direct TI equivalents: TLV331 (pin-for-pin with LMV331 SN3T1G; same device family).
Cross-vendor options (single-supply, 1.8–5.5 V, rail-to-rail I/O) include ST TS321 and On Semiconductor NCV331. Note: pinouts and ranges can vary; verify with datasheets or TI’s cross-reference tool.
