Visão Geral

Description

LMV331SN3T1G is a Texas Instruments single-channel, low-power voltage comparator. It’s designed for battery-powered and portable electronics. It operates from a 2.7 V to 5.5 V supply and draws very low current, making it ideal for threshold detection, level sensing, and power-management tasks. The device compares two analog inputs and outputs a digital signal indicating which input is higher. The SN3T1G suffix indicates a small surface-mount package (Tape & Reel). For exact electrical specs (input common-mode range, offsets, propagation delay) and pinout, consult the TI datasheet.

Equivalent

Likely equivalents (same type and function; verify pinout/voltage):
- TI TLV331 (same single-supply, rail-to-rail input comparator; cross-family part)
- Automotive variant: LMV331Q/LV331Q (same device family, automotive grade)
- On Semiconductor: NCV331 (low-power comparator)
- Analog Devices: ADCMP331 (analog comparator in similar family)
Note: exact cross-ref depends on package and voltage/temperature specs. Use a distributor TI cross-reference or datasheet to confirm fit for LMV331SN3T1G.

Features

LMV331SN3T1G features:
- Single-channel voltage comparator
- Wide single-supply operation with rail-to-rail input and output
- Low input offset voltage and low bias current (low power)
- High speed with fast propagation delay
- TTL/CMOS-compatible output
- Very low quiescent current
- 3-pin SC-70/SOT-23 package (SN3) with RoHS-compliant, lead-free packaging
(Ideal for battery-powered/small-form applications requiring fast, rail-to-rail comparison.)

Pinout

- Pin count: 5 pins (SOT-23-5 package).
- Function: Single-channel voltage comparator. Compares two input voltages ( +IN and −IN ) and outputs a digital signal, using a single supply (Vcc and GND).

Manufacturer

- Manufacturer: Texas Instruments (TI)
- What kind of company: American multinational semiconductor company that designs and manufactures analog, mixed-signal, and embedded processing ICs; headquartered in Dallas, Texas, and one of the world’s largest chip makers.

Application

LMV331SN3T1G is a low‑power, single‑channel voltage comparator. Typical application areas include:
- Battery-powered systems for voltage monitoring and reset generation
- Power-supply and DC–DC converter feedback and threshold detection
- Sensor interfaces (thermistors, photodiodes, Hall sensors) with voltage level comparison
- Microcontroller interfacing and digital signal conditioning (level detection with hysteresis)
- Zero-crossing and line-sensing for AC and motor-control circuits
- Window/threshold detectors and alarm/protection circuits in consumer, industrial and automotive equipment

Package

SC-70-3 (3-pin) small SMD package.
