CrossChip CC6920BSO-30A 单芯片差分霍尔电流传感器产品概述

一、产品定位与核心价值

CC6920BSO-30A是成都芯进电子(CrossChip)推出的单芯片差分霍尔电流传感器,专为中低功率电力电子系统的高精度、双向电流检测需求设计。区别于传统分流器+运放的组合方案,该传感器集成霍尔元件、信号调理电路于单芯片,无需外部放大电路即可实现宽范围电流检测,同时具备高隔离性、低功耗、宽温适应性等优势,可显著简化系统设计、降低成本,适用于工业自动化、新能源、消费电子等多领域。

二、关键参数详解

以下为产品核心参数及实际应用意义:

  1. 电流测量范围:-30A~30A(双向检测)
    支持正反向电流同步检测,无需切换电路即可适配电机正反转、电池充放电等双向电流场景。
  2. 工作电压:3.3V
    匹配主流MCU的IO电压,无需电平转换,简化系统供电设计。
  3. 隔离电压:3500Vrms
    满足IEC 61010等安全标准,可有效隔离高压被测电路与低压控制电路,保障人员与设备安全。
  4. 灵敏度:44mV/A
    线性度优异,输出电压与被测电流呈严格线性关系(例:30A时输出1.32V,-30A时输出-1.32V),便于MCU直接采样。
  5. 待机电流:20mA
    低功耗设计,适合电池供电或长期待机的系统(如便携式测试设备)。
  6. 工作温度:-40℃~+125℃
    覆盖工业级宽温范围,可稳定工作于高温车间、户外设备等恶劣环境。
  7. 带宽与响应时间:250kHz/1μs
    高带宽支持高频电流检测(如开关电源的纹波电流),1μs响应时间确保实时性,适配快速动态负载场景。
  8. 电流端电阻:0.9mΩ
    导通损耗极低(30A时仅约0.81W),几乎不影响被测电路效率,避免额外散热设计。

三、核心技术特性

  1. 单芯片集成,简化设计
    内置霍尔元件、差分放大、温度补偿电路,无需外部运放、分压电阻等元件,PCB布局更紧凑,降低BOM成本与设计复杂度。
  2. 差分霍尔抗干扰
    采用差分检测原理,可抑制共模噪声(如电源波动、电磁干扰),在工业现场复杂电磁环境下仍能保持±1%以内的精度。
  3. 双向检测无极性切换
    无需额外切换电路即可同时检测正反向电流,适配电机驱动、电池充放电等双向电流场景,减少电路故障点。
  4. 宽温稳定性
    内置温度补偿模块,在-40℃~+125℃范围内,灵敏度漂移控制在极小范围,确保不同温度下检测精度一致。
  5. 低功耗长寿命
    待机电流仅20mA,工作时功耗可控,结合SOP-8封装的可靠性,适合长期连续工作的工业设备。

四、典型应用场景

  1. 工业自动化
    伺服驱动器、变频器的电机电流检测(正反转双向控制);机器人关节的扭矩控制反馈。
  2. 新能源领域
    小型充电桩的输出电流监测;便携式储能设备的充放电电流检测;新能源汽车辅助系统(如空调、灯光)的电流监控。
  3. 消费电子
    大功率充电器(如65W以上)的电流限制与保护;智能家电的功率监测(如变频空调、洗衣机)。
  4. 电力监控
    配电系统的小电流回路检测;UPS电源的输出电流反馈。

五、封装与可靠性设计

  • 封装形式:SOP-8贴片封装,尺寸小(约5.2×6.2mm),适配高密度PCB设计,支持自动化焊接,生产效率高。
  • 隔离可靠性:3500Vrms隔离电压满足安全标准,确保高低压电路隔离安全,避免漏电风险。
  • 耐环境性:SOP-8封装具备良好的防潮、抗振动性能,适合工业现场的振动环境。

六、选型与使用注意事项

  1. 电流范围匹配:仅适用于-30A~30A双向电流,若被测电流超出范围需选择同系列更高量程型号(如CC6920BSO-50A)。
  2. 供电要求:工作电压需稳定在3.3V±5%,避免过压损坏芯片。
  3. PCB布局:电流输入端应尽量短直,减少线阻影响;远离高频干扰源(如开关电源变压器),避免电磁耦合。
  4. 采样精度:若需更高精度,可对输出电压进行校准(因芯片存在小范围初始偏移)。

这款传感器凭借集成度高、性能优异、成本可控的特点,已成为中低功率电流检测领域的主流选择,可有效满足工业、新能源等场景的多样化需求。
