CrossChip CC6921SO-50A 隔离式电流传感器产品概述

一、产品定位与核心价值

CC6921SO-50A是成都芯进电子(CrossChip)推出的工业级高带宽隔离式电流传感器,专为中功率系统的宽温、高速、安全电流检测需求设计。产品整合低损耗电流通路、高压隔离防护与快速动态响应特性,可实现双向电流精准测量,为工业自动化、新能源、电力电子等领域提供可靠的电流反馈与保护功能。

二、核心性能参数深度解析

结合关键参数,产品性能优势体现在以下维度:

  1. 电流检测能力:支持-50A~50A双向电流测量,覆盖中功率设备常见电流范围;电流端电阻仅0.45mΩ,大幅降低被测回路功耗(如50A时损耗仅1.125W),不影响原电路工作状态。
  2. 隔离安全特性:具备1000Vrms交流隔离电压,可有效隔离高低压电路,保护后端控制电路免受高压冲击,符合工业与新能源领域安全规范。
  3. 动态响应性能:带宽达250kHz,响应时间(tr)1.2μs,能精准捕捉高频电流变化(如开关电源瞬态电流、伺服电机动态电流),满足高速控制系统反馈需求。
  4. 电气与环境适应性:工作电压5V(典型值),待机电流20mA,功耗低;工作温度范围-40℃~+125℃,覆盖工业级极端温度场景(如户外光伏逆变器、车载电子),可靠性高。
  5. 输出特性:灵敏度40mV/A,输出电压与被测电流线性正比,无需复杂校准即可直接接入ADC(如50A时输出2V,适配3.3V参考电压的ADC),简化系统设计。

三、封装与系统集成优势

产品采用SOP-16-W贴片封装,体积紧凑(与标准SOP-16兼容),适合小型化设备高密度集成,同时具备:

  • 内置隔离层:无需外部光耦或变压器,减少BOM成本与PCB空间;
  • 双向检测简化设计:输出极性随电流方向变化,无需额外方向判断电路;
  • 宽温可靠性:工业级工艺保障极端温度下线性度与精度稳定,降低系统维护成本。

四、典型应用场景

CC6921SO-50A的性能匹配多领域需求,典型应用包括:

  1. 工业自动化:伺服驱动器、变频器的电流反馈与过载保护,实现电机精准控制;
  2. 新能源领域:光伏逆变器MPPT电流监控、电动车BMS电池充放电电流检测;
  3. 电力电子设备:开关电源、UPS的电流环路控制,提升电源转换效率;
  4. 智能电网:配电终端电流测量、故障电弧检测,保障电网安全;
  5. 车载电子:汽车EPS电机电流检测、充电桩充电电流监控(适配车载宽温环境)。

五、设计注意事项

为保障性能稳定,系统设计需注意:

  • 电压范围:确保输入电压稳定在4.5V~5.5V(典型值5V),避免过压损坏;
  • 散热考虑:大电流(>30A)持续工作时,需为电流端预留散热空间(如PCB铜箔加宽);
  • 抗干扰布线:隔离端与被测端布线保持距离,避免交叉干扰;
  • 输出滤波:若需抑制高频噪声,可在输出端并联10nF~100nF陶瓷电容。

CC6921SO-50A凭借高带宽、宽温、低损耗与隔离安全特性,成为中功率电流检测场景的高性价比选择,可有效提升系统可靠性与集成度。

Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.

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
