CrossChip CC6921BSO-100A 电流传感器产品概述

成都芯进(CrossChip)推出的CC6921BSO-100A是一款隔离式双向电流传感器,针对工业控制、新能源、汽车电子等领域的宽量程、高响应需求优化设计,具备宽电流检测范围、高带宽、低损耗等核心特性,同时满足工业级宽温与安全隔离要求。

一、产品定位与核心价值

CC6921BSO-100A定位于中大功率双向电流检测场景,核心价值体现在:

  1. 覆盖正负电流全量程,适配电机正反转、电源双向转换等场景;
  2. 250kHz高带宽与1us快速响应,满足高频信号与动态控制需求;
  3. 0.45mΩ低电流端电阻,大幅降低功率损耗,提升系统能效;
  4. 1000Vrms电气隔离,保障高压端与控制端的安全隔离;
  5. 工业级宽温范围(-40℃~+125℃),适应极端环境下的稳定工作。

二、关键性能参数深度解析

1. 电流检测与精度

  • 量程范围:-100A~100A双向检测,无需切换量程即可覆盖正负电流,适合电机控制、电池充放电等双向电流场景;
  • 灵敏度:13.2mV/A(线性输出),电流与输出电压呈正比,100A时输出1.32V,适配3.3V系统的ADC采集(无需额外电平转换);
  • 电流端电阻:仅0.45mΩ,通过电流时的功率损耗极低(如100A时损耗仅4.5W),避免发热影响系统稳定性。

2. 动态与带宽性能

  • 带宽:250kHz,可准确检测高频电流信号(如开关电源纹波、伺服电机高频电流);
  • 响应时间:1us(上升时间),满足快速闭环控制(如伺服电机速度环、电流环的实时反馈)。

3. 电气与可靠性参数

  • 工作电压:3.3V单电源供电,兼容主流MCU/SoC的IO电压,简化系统设计;
  • 隔离电压:1000Vrms(AC),符合工业安全标准,有效隔离高压端(如电机、逆变器)与低压控制端;
  • 工作温度:-40℃~+125℃,覆盖汽车、工业现场的极端温度环境;
  • 待机电流:20mA,低功耗设计适合对电源效率要求高的场景(如车载电子)。

三、典型应用场景

CC6921BSO-100A适配多行业的电流检测需求,典型场景包括:

  1. 工业伺服电机控制:双向电流检测满足电机正反转,250kHz带宽与1us响应支撑高精度动态控制;
  2. 新能源汽车:BMS电池充放电电流监测、电机控制器电流反馈,宽温范围适应车载环境;
  3. 光伏逆变器:并网电流检测、MPPT功率跟踪,隔离电压保障光伏高压端与控制端安全;
  4. 工业电源监测:开关电源输出电流检测、UPS电源负载电流监测,低损耗提升电源效率;
  5. 机器人关节驱动:伺服关节电机电流反馈,快速响应支撑机器人精准运动控制。

四、封装与安装特性

采用SOP-16-W贴片封装,体积紧凑(符合标准SOP16尺寸),适配自动化贴片生产,同时便于在高密度PCB上布局;引脚设计合理,电流输入端与信号输出端分离,降低电磁干扰(EMI)影响。

五、使用注意事项

  1. 电源需采用3.3V±5%的稳定电压,避免电压波动影响输出精度;
  2. 电流输入端需按照 datasheet 规范接线(注意引脚定义),确保双向电流检测的准确性;
  3. 隔离端(电流输入)与非隔离端(信号输出)需保持至少2mm的爬电距离,满足绝缘要求;
  4. 工作温度需控制在-40℃~+125℃范围内,避免超温导致性能下降;
  5. 输出信号可直接接入12位或16位ADC(如STM32的ADC模块),无需额外放大电路。

总结

CrossChip CC6921BSO-100A通过平衡宽量程、高带宽、低损耗、安全隔离与工业级可靠性,成为工业控制、新能源、汽车电子等领域的高性价比电流检测方案。其紧凑封装与3.3V兼容设计,进一步简化了系统开发流程,适合对电流检测精度与动态性能有较高要求的应用场景。

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.
