CC6905S8-3FB005 电流传感器产品概述

一、产品定位与核心设计思路

CC6905S8-3FB005是成都芯进(CrossChip)推出的线性霍尔效应电流传感器,针对**±5A中低电流范围**的高精度、宽环境适应性检测需求设计,兼顾小体积、低功耗与快速响应特性。产品采用非接触式检测原理,避免传统分流电阻的功耗与安全隐患,同时通过电气隔离设计保障前后级电路安全,可广泛适配工业控制、电机驱动、电源管理等场景。

二、关键性能参数与应用价值

1. 电流测量范围:±5A(双向)

覆盖常见中低电流场景(如小型电机、电池充放电、开关电源输出),无需额外量程切换,简化电路设计。双向检测支持直流/交流电流同时测量,适配电机正反转、电池充放电等双向电流场景。

2. 工作电压与功耗:3.3V供电,待机电流10mA

适配主流嵌入式系统(MCU、PLC)的低电压供电,待机功耗低,适合需要休眠唤醒的便携式/低功耗设备(如移动电源、笔记本电脑),无需额外升压电路即可集成。

3. 电气隔离能力:100Vrms隔离电压

实现被测电流端与输出端的电气隔离,避免高压端对低压控制电路的干扰或损坏。例如在电机驱动中,可隔离高压电机绕组与低压MCU控制端,提升系统安全性。

4. 灵敏度与线性度:264mV/A(线性)

输出电压与被测电流呈严格线性关系,无需复杂校准即可实现高精度采样(误差可忽略),便于MCU直接AD转换,降低系统开发难度。

5. 宽温与可靠性:-40℃~+125℃工作温度

覆盖工业现场(户外控制柜、车间)、汽车发动机舱等恶劣环境,满足高低温循环、振动等可靠性要求,可在极端温度下稳定工作6000小时以上(工业级标准)。

6. 带宽与响应速度:230kHz带宽,1.5μs响应时间

支持高频电流纹波检测(如开关电源、高频电机),瞬态响应快——短路发生时可在1.5μs内触发保护电路,避免功率器件损坏,提升系统抗故障能力。

7. 低损耗设计:电流端电阻0.5mΩ

被测电流通路内阻极小,功率损耗(I²R)可忽略(如5A电流下损耗仅12.5mW),不影响被测电路的正常工作,尤其适合对效率要求高的电源、电机系统。

三、封装与集成优势

产品采用SOP-8贴片封装,体积紧凑(符合工业标准封装尺寸:5.2×6.2×1.7mm),便于在PCB板上紧凑布局,适合小型化产品(如便携式设备、微型变频器)。封装引脚定义清晰,集成度高——仅需外接电源滤波电容即可工作,无需额外外围电路,进一步简化系统设计。

四、典型应用场景

  1. 小型电机驱动:无人机无刷电机、扫地机器人电机的电流检测与过流保护,宽温适应不同工作环境(如户外无人机、室内家电);
  2. 开关电源管理:LED驱动电源、笔记本适配器的输出电流检测,230kHz带宽可准确捕捉纹波电流,保障电源稳定;
  3. 工业控制模块:PLC IO模块、小型变频器的电流监控,-40~125℃宽温满足工业现场高低温需求;
  4. 电池管理系统(BMS):小型储能电池、电动车辅助电池的充放电电流检测,低功耗适合电池供电的便携式BMS;
  5. 消费电子:移动电源、智能手表的充电电流检测,小体积封装适配便携设备的紧凑空间。

五、产品核心优势总结

  • 宽环境适应:-40~125℃工作温度,覆盖工业、汽车、消费电子多场景;
  • 高精度快速响应:264mV/A线性输出+1.5μs响应,满足高频瞬态检测需求;
  • 安全低耗:100Vrms隔离+0.5mΩ低阻,保障系统安全且不影响被测电路;
  • 易集成:3.3V供电+SOP-8封装,适配主流嵌入式系统,简化设计;
  • 高可靠性:非接触式霍尔检测,无机械磨损,寿命长(MTBF≥10万小时)。

CC6905S8-3FB005通过平衡性能、体积与成本,成为中低电流检测场景的高性价比选择,尤其适合对宽温、响应速度有要求的工业与消费电子领域。

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.
