CrossChip CC6904SO-30A 电流传感器产品概述

CC6904SO-30A是成都芯进(CrossChip)推出的一款隔离式双向电流传感器,针对工业控制、新能源、电力监控等领域的电流检测需求优化设计,兼具宽测量范围、快速响应、高隔离性能与小体积特点,适配多种复杂应用场景。

一、产品定位与核心设计目标

该传感器聚焦**“高性能+高集成度+低成本”** 平衡,核心设计围绕三大需求:

  1. 覆盖工业与新能源常见电流范围(-30A~30A双向);
  2. 满足高压系统隔离安全要求(2000Vrms隔离);
  3. 适配高速动态电流检测(80kHz带宽、2us响应时间)。

其定位为中小功率系统的电流检测核心器件,替代传统分流器+运放+隔离的复杂方案,简化电路设计。

二、关键性能参数深度解析

1. 电流测量与隔离能力

  • 双向检测范围:-30A~30A,支持交流/直流电流同步检测,无需区分电流方向,适配正反向负载场景;
  • 隔离电压:2000Vrms(AC),满足IEC 61010等安规标准,有效隔离高压侧(如电机绕组、光伏逆变器)与低压控制端(MCU、PLC),避免共模干扰与安全隐患。

2. 信号输出与功耗

  • 灵敏度:44mV/A,线性度优异(结合电流端1.5mΩ低内阻,输出与被测电流呈正比),直接匹配3.3V MCU的ADC输入范围(无需额外放大);
  • 工作电压:3.3V单电源供电,简化电源设计,适配主流微控制器系统;
  • 待机电流:5mA,低功耗特性适合长时间待机的系统(如智能电表、便携式测试设备)。

3. 动态性能与环境适应性

  • 带宽:80kHz,覆盖电机控制中的PWM高频电流(如变频电机的载波频率)、开关电源的瞬态电流;
  • 响应时间:2us(上升时间),可快速跟踪电流突变(如电机启动、负载切换),满足动态控制需求;
  • 工作温度:-40℃~+125℃,满足工业级环境(如户外光伏逆变器、车载辅助系统)与极端温度场景。

4. 插入损耗与封装

  • 电流端电阻:1.5mΩ极低内阻,插入损耗小(I²R功耗可忽略),不影响被测电路的正常工作;
  • 封装:SOP-8小封装(5.2mm×6.2mm),适配PCB密集布局,降低系统体积与成本。

三、典型应用场景

基于上述性能,CC6904SO-30A可广泛应用于以下领域:

  1. 工业电机控制:伺服电机、变频电机的电流闭环控制(如机床、机器人关节);
  2. 新能源系统:光伏逆变器低压侧电流检测、车载辅助系统(如电动座椅、空调)电流监测;
  3. 电力监控:小型配电系统、UPS电源、智能电表的电流测量与过载保护;
  4. 消费电子与家电:变频空调、滚筒洗衣机的电机电流检测(实现节能与故障诊断);
  5. 测试测量设备:便携式电流钳、数据采集卡的电流检测模块。

四、应用便捷性与可靠性

  • 电路简化:无需额外磁芯、隔离放大器或信号调理电路,单电源+直接ADC采样即可实现电流检测;
  • 可靠性设计:宽温范围、低内阻减少发热,2000Vrms隔离通过长期可靠性测试,适合工业级长期运行;
  • 兼容性:SOP-8封装兼容标准PCB贴装工艺,便于批量生产。

总结:CC6904SO-30A以高性价比实现了隔离、宽范围、快速响应的电流检测,是中小功率系统电流监测的优选器件,可有效降低系统设计复杂度与成本。

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
