LM393MM/TR 产品概述 — 双路比较器（HGSEMI 华冠）
一、产品简介
LM393MM/TR 为 HGSEMI（华冠）出品的双路电压比较器，封装为 MSOP-8，适用于对电压进行高速、低功耗比较的通用场合。器件采用开漏输出结构，输出电平兼容 CMOS 逻辑，通过外接上拉电阻即可与多种逻辑电源配合工作。器件支持宽电源电压范围和单/双电源供电方式，适配多种系统设计需求。
二、主要特性
- 比较器通道数：双路（两个独立比较器）
- 输入失调电压 Vos：典型 1 mV
- 输入偏置电流 Ib：典型 100 nA
- 输入失调电流 Ios：典型 5 nA
- 静态电流 Iq：典型 600 μA（器件总体静态电流）
- 输出类型：开漏（需上拉电阻）
- 输出兼容：CMOS 电平兼容（通过合适上拉）
- 工作温度范围：0 ℃ ~ +70 ℃
- 最大电源宽度：36 V
- 单电源供电：2 V ~ 32 V
- 双电源供电（Vee ~ Vcc）：±16 V
- 封装：MSOP-8；型号后缀 “/TR” 表示带盘带卷装（Tape & Reel）
三、功能描述
每路比较器比较两个输入端电压，当非反相输入高于反相输入时，输出导通情况由外部上拉决定（开漏仅能下拉至低电平）。器件内部采用低功耗设计，静态电流小，适合电池供电或对功耗敏感的系统。输入偏置和失调电流较小，有利于提高比较精度和减少漂移。
四、典型应用场景
- 电压监测与欠压、过压检测
- 开关模式电源的电压比较与参考检测
- 信号整形、脉冲宽度检测与门限触发
- 电池管理与便携设备电源管理
- 工业控制与数据采集前端比较电路
五、使用建议与注意事项
- 由于输出为开漏结构，必须外接合适阻值的上拉电阻；上拉电压不得超过器件允许的工作电源范围。
- 在要求确定的逻辑高电平时，上拉电阻与负载能力需兼顾开关速度与功耗。
- 避免将输入端悬空；未连接输入可能导致不确定状态。
- 在高噪声环境或长布线时，建议在输入端加滤波或施加滞回以避免抖动。
- 工作温度请控制在 0 ℃ ~ +70 ℃ 范围内，超出可能影响参数稳定性。
六、封装与订购信息
LM393MM/TR 为 MSOP-8 小封装，适合空间受限的 PCB 设计；后缀 /TR 表示盘带卷装，便于贴片生产线使用。品牌为 HGSEMI（华冠），型号在采购时请确认封装和包装方式以满足生产需求。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Sourcing availability signal
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
Examples of how common component sourcing requests are organized.
Typical RFQ scenarios based on the WMSIC form fields, catalog data, manual review steps, and shipment preparation workflow.
The buyer shares the full part number, package requirement, quantity, destination, and available product photos so the quotation can record the exact version under review.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
