CrossChip CC6921BSO-50A 隔离式电流传感器产品概述

成都芯进电子(CrossChip)推出的CC6921BSO-50A是一款隔离式霍尔电流传感器,针对中功率电流检测场景优化,具备宽温范围、高频响应、低损耗等核心特性,广泛适配工业自动化、新能源辅助系统、开关电源等领域。

一、品牌与产品定位

CrossChip(芯进电子)是国内专注功率半导体与传感器研发的厂商,核心产品覆盖电流传感器、霍尔器件、功率MOSFET等,服务工业控制、汽车电子、新能源等行业。CC6921BSO-50A作为其隔离式电流传感器系列的一员,定位为中低功率场景的高精度电流检测解决方案,重点解决高低压电路隔离、宽温环境适配、高频电流响应等痛点。

二、关键性能参数深度解析

CC6921BSO-50A的参数设计针对性强,覆盖电流检测、电气安全、动态性能等核心维度:

1. 电流检测核心参数

  • 双向电流范围:-50A~50A(支持正负电流测量,无需额外切换电路);
  • 低导通损耗:电流端电阻仅0.45mΩ,50A峰值电流下的导通损耗为0.45mΩ×(50A)²=1.125W,热效应可控,无需额外散热;
  • 线性输出灵敏度:26.4mV/A,输出电压与被测电流呈线性关系,无需复杂校准,可直接对接3.3V系统的ADC采样。

2. 电气安全与供电特性

  • 隔离电压:1000Vrms(满足高低压电路电气隔离,避免干扰与安全隐患);
  • 低功耗供电:工作电压3.3V(适配主流MCU/控制器),待机电流20mA(工作/待机模式功耗明确,便于系统功耗管理)。

3. 动态与环境适应性

  • 高频响应:带宽250kHz(覆盖开关电源、伺服电机等高频电流信号),响应时间1μs(过流保护场景下可快速触发,避免器件损坏);
  • 宽温范围:-40℃~+125℃(满足工业户外、汽车发动机舱等极端温度环境)。

三、核心技术优势

CC6921BSO-50A的参数设计转化为实际应用优势,体现在以下三点:

  1. 隔离安全与低损耗平衡:1000Vrms隔离电压实现高低压侧电气隔离,同时0.45mΩ低阻避免大电流下的能量损耗,适合连续工作场景;
  2. 宽温高频适配性:-40~125℃宽温覆盖工业与汽车级应用,250kHz带宽+1μs响应满足开关电源(如LLC、PFC)、伺服电机的动态电流检测;
  3. 简化系统设计:双向电流检测无需额外切换电路,3.3V单电源供电,线性输出易对接MCU,降低系统BOM成本与开发难度。

四、典型应用场景

结合参数优势,CC6921BSO-50A适用于以下场景:

  1. 工业自动化:伺服电机驱动、变频器、PLC的电流监测与过流保护;
  2. 新能源辅助系统:电动汽车(EV)的DC-DC转换器、充电枪电流检测,储能系统小功率模块的电流反馈;
  3. 开关电源:服务器电源、工业电源的PFC电路、LLC谐振电路的电流闭环控制;
  4. 电力电子设备:不间断电源(UPS)、逆变器的电流监测与过载保护。

五、选型与应用注意事项

  1. 电流范围匹配:实际工作电流需控制在50A峰值以内,避免过载导致精度下降或器件损坏;
  2. 隔离需求确认:若系统需要2000Vrms以上隔离,需选择CrossChip其他高隔离型号;
  3. 温度环境适配:若工作温度超过125℃,需降额使用(建议电流不超过额定值的80%);
  4. 采样电路设计:输出为模拟电压(26.4mV/A),需通过12位以上ADC采样,若需隔离采样,可搭配隔离ADC或光耦。

这款传感器以其高性价比、宽适配性,成为工业控制与新能源领域中低功率电流检测的优选方案之一。

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
