ACS773LCB-100B-PFF-T 产品概述
一、产品简介
ACS773LCB-100B-PFF-T 是 ALLEGRO（美国埃戈罗）推出的一款高精度霍尔效应电流传感器，面向大电流测量场景。器件采用隔离式霍尔传感结构，支持正负双向电流检测，能在苛刻电气环境中提供稳定、线性的模拟输出，便于与MCU/ADC直接接口。
二、主要技术参数
- 电流测量范围：±100 A（双向测量）
- 工作电压：3.0 V ~ 3.6 V
- 隔离电压：4800 Vrms（绝缘耐压）
- 灵敏度：13.2 mV/A
- 待机电流：10 mA
- 工作温度：-40 ℃ ~ +150 ℃
- 带宽：200 kHz（-3 dB）
- 响应时间（tr）：2.5 μs
- 封装：未定（请参照官方数据手册确认）
三、功能与特性
- 高精度线性输出：灵敏度 13.2 mV/A，可直接输出与电流成比例的模拟电压信号。
- 双向检测：支持正负电流测量，零电流点通常位于电源电压的中点（约 VCC/2），便于差分测量。
- 高隔离耐压：4800 Vrms 的隔离等级，适合电气隔离要求高的应用。
- 快速响应与宽带宽：2.5 μs 响应时间与 200 kHz 带宽，适合开关电源、逆变器等快速动态场景。
- 系统级保护：内置过流保护与上电复位功能，提高系统可靠性。
四、典型应用场景
- 电机驱动与伺服控制（电流闭环反馈）
- 开关电源与逆变器电流监测
- 电池管理系统（BMS）与储能系统
- 工业自动化、电力电子保护与测量模块
五、设计与使用建议
- 输出接口：输出为模拟电压，与电源成比例；在双向测量时应将 ADC 参考与 VCC/2 对齐或进行差分采样以提高精度。
- 去耦与滤波：建议在 VCC 与 GND 之间加入合理去耦电容，并根据带宽需求在输出端并联小电容或 RC 低通滤波器以抑制高频噪声。
- 热管理：尽管工作温度范围宽，但在高电流持续应用中需关注封装散热与 PCB 布局，确保温升可控以维持精度。
六、注意事项
- 封装与引脚：本描述未包含具体封装与引脚定义，请以 ALLEGRO 官方数据手册为准。
- 校准：为获得最高测量精度，建议在系统中进行偏置与增益校准，考虑温漂补偿。
- 电磁兼容：高电流环境容易产生磁场与干扰，布线和屏蔽设计应合理安排以降低误差。

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.
