CC6921BSO-10A 电流传感器产品概述

一、产品定位与核心优势

CC6921BSO-10A是成都芯进(CrossChip)推出的工业级隔离式双向电流传感器,针对中功率电流检测场景设计,核心定位为“高精度、宽适配、高可靠”的电流监测方案。其核心优势可概括为:

  • 双向电流兼容:无需额外电路处理正负电流,简化系统设计;
  • 强隔离防护:1000Vrms隔离电压,保障高低压电路安全隔离;
  • 宽频快响应:250kHz带宽+1us响应时间,覆盖高频信号与瞬态变化;
  • 低损耗设计:0.45mΩ电流端电阻,几乎不影响被测电路;
  • 宽温适应:-40℃~125℃工作范围,满足极端环境需求。

二、基础参数与性能指标

1. 电流检测核心参数

  • 测量范围:-10A~10A(双向直流/交流兼容);
  • 灵敏度:132mV/A(线性输出,与电流值成正比,便于ADC采集);
  • 电流端电阻:0.45mΩ(低阻抗,10A电流下损耗仅0.045W)。

2. 电气与隔离特性

  • 工作电压:3.3V(适配主流MCU/DSP供电,无需升压);
  • 待机电流:20mA(静态功耗低,适合长期运行场景);
  • 隔离电压:1000Vrms(符合IEC 61010等工业安全标准)。

3. 动态性能

  • 带宽:250kHz(支持50/60Hz工频+谐波、高频开关电流检测);
  • 响应时间(tr):1us(快速捕捉电机启动浪涌、短路故障等瞬态变化)。

4. 环境与封装

  • 工作温度:-40℃~+125℃(覆盖工业现场、光伏电站等极端环境);
  • 封装:SOP-16-W(贴片式,体积紧凑,易集成于PCB板)。

三、关键性能亮点解析

1. 双向电流检测的实用价值

传统单向传感器需额外继电器或极性切换电路处理负电流,而CC6921BSO-10A直接支持-10A~10A双向检测,可简化电机正反转控制、电池充放电监测等场景的电路设计,减少元件数量与成本。

2. 1000Vrms隔离的安全保障

在光伏逆变器、变频器等高压场景中,被测电路(高压侧)与控制电路(低压侧)需严格隔离。该传感器的1000Vrms隔离电压可有效阻断高压干扰,保护MCU、DSP等敏感元件,避免击穿风险。

3. 宽频与快速响应的适配性

  • 250kHz带宽可覆盖变频器输出电流(含高频谐波)、开关电源纹波电流等场景;
  • 1us响应时间能快速捕捉电机启动浪涌电流、短路故障等瞬态变化,为保护系统提供及时的信号输入(如触发过流保护的延迟<1us)。

4. 低电流端电阻的损耗控制

0.45mΩ的电流端电阻远低于普通传感器(通常>1mΩ),10A电流下仅产生0.045W损耗,几乎不影响被测电路的正常工作,尤其适合电池管理系统(BMS) 等对功耗敏感的场景。

四、典型应用场景

1. 工业自动化

  • 变频器、伺服驱动器的电机电流闭环控制(正反转双向电流);
  • PLC、工业机器人的负载电流监测;
  • 机床、 conveyor 等设备的过流保护。

2. 新能源行业

  • 光伏逆变器的并网交流电流检测;
  • 储能电池系统的充放电双向电流监测;
  • 电动汽车充电桩的交流/直流电流控制。

3. 电力监测与保护

  • 智能电表的小电流计量(<10A场景);
  • 配电系统的过流/短路保护(瞬态电流快速检测);
  • UPS电源的负载电流监测。

4. 其他场景

  • 医疗设备的低电流检测(隔离要求高);
  • 测试仪器的高频电流信号采集。

五、封装与可靠性

  • SOP-16-W封装:贴片式设计,体积紧凑(约7.8mm×4.9mm),焊接工艺成熟,适合批量生产;引脚布局合理,便于电路布线与信号隔离。
  • 宽温可靠性:经过-40℃~125℃高低温循环测试(1000次),无性能衰减,可稳定运行于寒冷的北方工业现场或高温的沙漠光伏电站。
  • 功耗稳定性:3.3V工作电压与20mA待机电流,功耗波动<5%,适配多数嵌入式系统的供电设计,无需额外电源模块。

CC6921BSO-10A凭借宽范围、高隔离、快响应及低损耗等特性,成为工业控制、新能源等领域的高性价比电流检测方案,可有效提升系统稳定性与安全性,降低设计复杂度。
