CC6902SO-5A 产品概述

一、产品简介

CC6902SO-5A 是成都芯进(CrossChip)推出的单芯片霍尔电流传感器系列中的 5A 版本,采用 SOP-8 封装、工作电压 5V、隔离耐压 2000Vrms。器件对双向直流/低频交流电流提供线性电压输出,灵敏度 400mV/A,适合对 ±5A 范围内的电流进行精确、隔离的测量与监控。

二、主要参数

  • 电流测量范围:-5A ~ +5A
  • 工作电压:5V
  • 隔离耐压(Vrms):2000Vrms
  • 灵敏度:400mV/A
  • 待机电流:典型 5mA
  • 工作温度:-40℃ ~ +125℃
  • 封装:SOP-8
  • 品牌:CrossChip(成都芯进)

三、核心特性

  • 高隔离:2000Vrms 隔离等级满足工业与电力电子系统的基本安全隔离要求,降低系统侧与测量侧之间的直接电气连接风险。
  • 高灵敏度:400mV/A 的增益使得在 ±5A 范围内输出电压摆幅充足,便于直接被 MCU/ADC 采样。
  • 低功耗待机:典型 5mA 待机电流,有利于功耗敏感应用。
  • 宽温度范围:-40℃ 至 +125℃,适应严苛环境工作。
  • 单芯片集成:简化外围设计,减少外部磁环或电路件,便于量产与可靠性控制。

四、典型应用场景

  • 电机控制与驱动电流检测(无刷直流电机、步进电机等)
  • 开关电源/DC-DC 转换器的电流监测与限流保护
  • 电池管理系统(BMS)中单节或整组电流监控
  • 逆变器与光伏系统的电流测量与保护
  • 工业自动化设备与仪表的隔离式电流传感

五、设计与使用建议

  • 输出参考:在 5V 供电下,器件通常在零电流时输出接近 VCC/2(约 2.5V),输出随电流按灵敏度线性变化(±400mV/A),建议在系统中按此比例进行标定与校准。
  • 电源去耦:在 VCC 引脚靠近器件放置 0.1µF 至 1µF 的高频去耦电容,以降低噪声与抑制瞬态。
  • PCB 布局:保持传感器与高电流导体的预定位置关系,保证导体穿过或靠近感应区域;对隔离侧与被测侧保持足够的爬电和间隙距离以符合隔离要求。
  • 温漂与校准:在精密测量场合,应在温度范围内评估偏置漂移和灵敏度偏差并做必要的软件或硬件校正。
  • 保护措施:对可能的瞬态过压、浪涌等,建议在系统端加入合适的抑制与保护元件以延长器件寿命。

六、封装与采购

CC6902SO-5A 采用 SOP-8 封装,便于自动化贴装与批量生产。适配常见的 SMT 工艺,便于与 MCU、ADC 等器件在同一 PCB 上实现紧凑布局。购买时请确认型号、温度等级与隔离需求,以保证系统可靠性。

总结:CC6902SO-5A 以其高灵敏度、2kVrms 隔离能力和宽温度适应性,适合要求小体积、低功耗且需隔离测量的电流监测应用。

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
