CC6921BSO-10A是成都芯进(CrossChip)推出的工业级隔离式双向电流传感器,针对中功率电流检测场景设计,核心定位为“高精度、宽适配、高可靠”的电流监测方案。其核心优势可概括为:
传统单向传感器需额外继电器或极性切换电路处理负电流,而CC6921BSO-10A直接支持-10A~10A双向检测,可简化电机正反转控制、电池充放电监测等场景的电路设计,减少元件数量与成本。
在光伏逆变器、变频器等高压场景中,被测电路(高压侧)与控制电路(低压侧)需严格隔离。该传感器的1000Vrms隔离电压可有效阻断高压干扰,保护MCU、DSP等敏感元件,避免击穿风险。
0.45mΩ的电流端电阻远低于普通传感器(通常>1mΩ),10A电流下仅产生0.045W损耗,几乎不影响被测电路的正常工作,尤其适合电池管理系统(BMS) 等对功耗敏感的场景。
CC6921BSO-10A凭借宽范围、高隔离、快响应及低损耗等特性,成为工业控制、新能源等领域的高性价比电流检测方案,可有效提升系统稳定性与安全性,降低设计复杂度。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
