LM239M/TR 四路比较器产品概述

一、产品基本定位与品牌信息

LM239M/TR是华冠半导体(HGSEMI) 推出的四路通用电压比较器,属于LM239系列的国产化衍生型号,采用SOP-14表面贴装封装。该器件专为多通道电压比较、阈值检测场景设计,具备高集成度、宽电源范围、低功耗等核心特点,可直接兼容TTL/CMOS数字电路,适用于工业控制、电池管理、消费电子等多领域,是进口LM239的高性价比替代方案。

二、核心电气参数解析

1. 多路集成设计

内置4路独立电压比较器,单芯片实现多通道并行比较,无需外部扩展额外比较器,有效减少系统元件数量、降低PCB占用面积,简化电路设计复杂度。

2. 精度与直流特性

  • 输入失调电压(Vos):典型值2mV,保证输入两端电压差处于低水平,提升阈值检测的准确性;
  • 输入失调电流(Ios):典型值5nA,输入偏置电流(Ib)25nA,低偏置设计减少对高阻抗输入信号的负载影响,适配传感器等弱信号源场景;
  • 静态电流(Iq):典型值800μA,低功耗特性可适配电池供电或对功耗敏感的系统,延长设备续航时间。

3. 速度与输出兼容性

  • 速度性能:传播延迟(tpd)1.3μs,响应时间(tr)1.3ns,在中速信号处理场景下具备良好实时性,满足多数阈值检测、脉冲比较需求;
  • 输出模式:兼容TTL/CMOS逻辑电平,无需额外电平转换电路,可直接与MCU、FPGA等数字控制单元接口,简化系统设计。

4. 电源灵活性

  • 单电源供电:支持3V~32V宽范围输入,适配5V、12V、24V等常见单电源系统;
  • 双电源供电:支持±1.5V±16V(对应VeeVcc为1.5V16V/-16V-1.5V),最大电源宽度(Vdd-Vss)达36V,可灵活适配正负电源的模拟电路场景;
  • 电源电压波动适应性强,降低系统对稳压电路的要求。

三、封装与工作环境

1. 封装形式

采用SOP-14表面贴装封装,尺寸紧凑(标准SOP-14封装尺寸),适合自动化贴片生产,便于高密度PCB布局,适配小型化电子设备。

2. 工作温度范围

支持**-25℃~+85℃** 工业级温度区间,可稳定工作于户外、车间等温差较大的环境,满足工业控制、车载电子等场景的可靠性要求。

四、典型应用场景

LM239M/TR的宽电源、多通道特性使其适用于以下场景:

  1. 电压阈值检测:电池管理系统(BMS)的过充/欠压保护、电源过压/欠压监测;
  2. 多通道信号比较:多路传感器(温度、压力)输出的阈值判断;
  3. 窗口比较器:通过外部电阻配置实现双阈值比较(如信号幅度是否在指定区间内);
  4. 电平转换:TTL与CMOS逻辑电平之间的双向转换,简化数字接口设计;
  5. 脉冲信号处理:PWM信号占空比检测、脉冲宽度比较;
  6. 工业控制:电机驱动电路的电流/电压反馈比较、PLC输入信号预处理。

五、产品核心优势

  1. 高集成度:单芯片四路比较器,减少系统元件数与设计成本;
  2. 电源灵活:单/双电源兼容宽范围,适配多种供电系统;
  3. 精度与速度平衡:中等失调电压+合理响应速度,满足通用比较需求;
  4. 接口兼容:TTL/CMOS双输出,简化数字电路对接;
  5. 工业可靠性:宽温范围+低功耗,适合恶劣环境应用;
  6. 成本优势:国产化替代方案,性能接近进口LM239,性价比更高。

LM239M/TR凭借稳定的电气性能与灵活的应用适配性,成为中低端电压比较场景的优选器件,可有效提升系统设计效率与可靠性。

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
