CrossChip CC6921SO-30A 霍尔电流传感器产品概述

一、产品定位与核心价值

成都芯进(CrossChip)推出的CC6921SO-30A是一款隔离式双向霍尔电流传感器,专为工业自动化、新能源、电力监控等领域的高精度、宽动态电流测量需求设计。其核心价值在于平衡了「宽量程覆盖、高动态响应、低功耗损耗」与「高隔离可靠性」,无需额外电流分流器即可实现安全的交直流电流检测,简化系统设计的同时提升测量精度,适配多场景下的中小功率电流监控需求。

二、关键性能参数深度解析

CC6921SO-30A的参数针对性解决了多场景痛点,核心特性如下:

1. 电流测量能力

支持**-30A~30A双向电流检测**,覆盖单相电机、光伏组串、储能电池组等常见中小功率设备的电流范围;电流端电阻仅0.45mΩ,远低于传统分流器的损耗(通常1mΩ以上),大幅降低测量回路发热与能量损耗,尤其适合对效率要求严格的新能源场景(如光伏逆变器、充电桩)。

2. 电气与信号特性

  • 工作电压5V(主流MCU供电电压),无需额外电平转换;
  • 待机电流仅20mA,低功耗设计适配电池供电或待机模式下的系统;
  • 灵敏度66.7mV/A(线性度优异,非线性误差通常<0.5%),输出信号与被测电流成正比例关系,无需复杂校准即可接入MCU/ADC,简化信号采集链路。

3. 隔离与可靠性

具备1000Vrms的隔离电压,可实现高低压侧(如电网与控制板)的安全隔离,避免高压对低压电路的干扰与损坏;工作温度范围覆盖-40℃~+125℃,满足工业级「极端环境」需求(如户外光伏逆变器、车载控制器),长期稳定性可靠。

4. 动态响应性能

250kHz带宽+1.2us响应时间(tr),能够精准捕捉快速变化的电流信号(如电机启动浪涌、开关电源高频纹波),适配高速控制回路(如变频器矢量控制、光伏MPPT追踪)的实时性要求。

三、典型应用场景适配

CC6921SO-30A的参数特性使其适配多类场景:

1. 工业自动化

  • 变频器(VFD)、伺服驱动器的电机电流闭环控制;
  • PLC/IO模块的配电监测;
  • 机器人关节电机的电流实时检测(宽温范围适配工业现场温差)。

2. 新能源领域

  • 光伏逆变器的组串电流测量(250kHz带宽支撑MPPT快速追踪);
  • 储能系统(锂电池组)的充放电双向电流监控;
  • 充电桩的电流计量(1000V隔离保障运维安全)。

3. 电力监控

  • 智能电表、配电终端(DTU)的电流监测;
  • 数据中心UPS电源的电流检测(低损耗减少系统功耗)。

四、封装与设计特点

采用SOP-16-W贴片封装,体积小巧(符合工业级贴片标准),适配自动化贴装生产线,降低生产难度;引脚布局合理,电流输入端与信号输出端物理隔离,进一步减少电磁干扰(EMI);封装材料耐温性优异,配合宽工作温度范围,适合高温/低温环境下的长期使用。

五、使用注意事项

  1. 电压范围:确保工作电压稳定在5V(±5%范围内,避免超压损坏芯片);
  2. 接线要求:电流输入端需采用低阻抗导线(如铜线),避免额外串联电阻影响测量精度;
  3. 隔离应用:若需高压隔离,确认被测电流回路与控制回路的电位差不超过1000Vrms;
  4. 温度校准:极端温度(-40℃/125℃)下,可根据 datasheet 提供的温度系数轻微校准,确保精度。

总结

CC6921SO-30A作为一款高性价比的隔离式霍尔电流传感器,以「宽量程、高带宽、低损耗、宽温可靠」为核心优势,覆盖工业、新能源等多领域的中小功率电流测量需求,是替代传统分流器、提升系统精度与安全性的理想选择。

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.
