概述

Description

LMV7239QDBVRQ1 is a Texas Instruments automotive-grade device in the LMV family. It is a low-power, rail-to-rail input/output analog IC (used as a general-purpose op-amp/comparator) intended for single-supply signal conditioning. The Q1 suffix means it’s qualified for automotive use (AEC‑Q100), and DBV is the 8-pin package code. Key strengths include low quiescent current and fast response with rail-to-rail I/O, suitable for sensor interfacing, buffering, level shifting, and precision monitoring in automotive and portable electronics. For exact specs (supply range, input/output behavior, bias currents, offset, bandwidth) refer to the TI datasheet.

Package

DBV package — 8-pin VSSOP (Very Small Outline Package).

Pinout

Pin count: 8 pins (VSSOP-8).
Function: LMV7239QDBVRQ1 is a voltage supervisor/reset IC. It monitors the supply voltage and generates a reset signal for a microcontroller or processor when the voltage falls below its threshold or on power-up. It typically includes a manual reset input and an active reset output.

Manufacturer

- Manufacturer: Texas Instruments (TI).
- What kind of company: TI is an American multinational semiconductor company that designs and manufactures analog and embedded processing integrated circuits.

Application

LMV7239QDBVRQ1 is a low-voltage, automotive-grade comparator. Typical applications:
- Battery-powered systems: undervoltage/overvoltage detection and cell monitoring
- Power-supply supervision and threshold-based reset/diagnostics
- Window comparators, zero-crossing detectors, and level-shifting front ends
- Automotive/industrial sensors, motor-control inputs, and general signal conditioning

Equivalent

LMV7239QDBVRQ1 is TI’s voltage supervisor/reset IC. Equivalents depend on reset threshold/features. Common cross-vendors include Microchip MCP131/132/133 voltage detectors and On Semiconductor voltage supervisor series. For exact cross, provide target Vcc range and desired reset threshold/behavior; I can give precise part-for-part substitutes.
