TSC2011IST 电流感应放大器产品概述

一、产品定位与核心功能

TSC2011IST是意法半导体(ST)推出的单路电流感应放大器,专为宽共模电压范围下的电流信号检测设计,具备低功耗、宽温工作、高抗干扰等核心特性。它可直接实现高压侧/低压侧电流精准感应,无需复杂的电平转换或隔离电路,能简化系统设计流程,降低硬件成本。

二、关键电气性能参数解析

该器件的性能参数覆盖电流感应全链路需求,核心指标如下:

  1. 共模电压范围:-20V至+70V,支持高压侧(如电池系统、电机驱动)和低压侧电流检测,无需额外高压隔离组件;
  2. 增益与带宽:固定增益60V/V,500kHz带宽,可满足中等频率(如开关电源、电机动态电流)的信号放大需求;
  3. 低功耗特性:典型静态电流1.5mA,适合电池供电或低功耗系统设计;
  4. 精度与温漂:输入失调电压500μV,失调电压温漂5μV/℃,保证-40℃~+125℃宽温范围内的检测精度;
  5. 抗干扰与噪声:共模抑制比(CMRR)120dB,有效抑制共模干扰;噪声密度37nV/√Hz@1kHz,适合微弱电流信号检测;
  6. 动态性能:压摆率7V/μs,可处理较快变化的电流信号;最大输出电流20mA,能直接驱动ADC、LED等负载。

三、工作环境与封装特性

  1. 宽温工作能力:-40℃至+125℃的工业级温度范围,可适应极端环境(如户外设备、车载电子);
  2. 封装形式:采用MSOP-8(8-MiniSO)小型封装,体积紧凑(约3mm×3mm),适合高密度PCB布局,节省系统空间;
  3. 电源兼容性:单电源2.7V~5.5V供电,兼容3.3V、5V等常见电源系统,无需双电源设计,降低电路复杂度。

四、典型应用场景

TSC2011IST的性能适配多领域电流感应需求,典型应用包括:

  1. 电池管理系统(BMS):监测锂电池充放电电流,实现过充、过放、短路保护;
  2. 开关电源设计:检测输出电流,触发过流保护,提升电源可靠性;
  3. 电机驱动系统:监测电机绕组电流,防止过载或堵转,保障电机安全运行;
  4. 工业自动化设备:如PLC、变频器的电流监测与故障诊断;
  5. 车载电子系统:(若符合应用要求)车灯、雨刮器等负载的电流检测。

五、应用注意事项

  1. 输入信号限制:输入差分电压需控制在-7V~+7V范围内,避免超过器件耐压导致损坏;
  2. 共模电压匹配:共模电压范围需与被测电路的电源/地电位匹配,确保信号输入稳定;
  3. 负载驱动:输出电流不超过20mA,需根据负载阻抗选择合适的限流或匹配电路;
  4. 精度校准:若对宽温精度要求较高,可通过软件校准补偿失调电压温漂,进一步提升检测精度。

该器件凭借宽共模电压、低功耗、宽温工作等优势,成为工业控制、电源管理、车载电子等领域电流感应的实用选择。

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.

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
