CrossChip CC6904SO-20A 单芯片霍尔电流传感器产品概述
CC6904SO-20A是成都芯进电子（CrossChip）针对工业级电流检测场景推出的单芯片集成霍尔电流传感器，核心聚焦20A双向电流测量，兼顾低功耗、高隔离、宽温适应性，是工业自动化、新能源、消费电子等领域的高性价比解决方案。
一、产品核心优势
该传感器通过单芯片集成霍尔效应感知、信号放大、温度补偿及线性化处理，无需额外外围元件即可实现稳定检测，核心优势包括：
- 高隔离安全：2000Vrms电气隔离能力，有效隔离被测高压回路与后端控制电路，避免高压击穿风险；
- 低功耗设计：3.3V单电源供电，待机电流仅5mA，适配电池供电或低功耗系统；
- 宽温可靠性：-40℃~+125℃工业级温区，满足户外、车载等极端环境需求；
- 动态响应优异：2μs响应时间+80kHz带宽，可精准捕捉瞬态电流（如电机启动浪涌、开关电源纹波）；
- 低损耗测量：电流端电阻仅1.5mΩ，20A量程下功率损耗仅0.6W，不影响被测电路效率。
二、关键性能参数详解

CC6904SO-20A的参数特性使其适配多领域电流检测需求：
- 工业自动化：伺服电机、变频器的电流闭环控制，宽温适应车间高低温环境，高带宽捕捉PWM电流；
- 新能源领域：
- 电池管理系统（BMS）：监测电池充放电电流，3.3V供电匹配BMS芯片，2kV隔离保护主板；
- 充电桩：慢充场景下的输出电流检测，宽温适应户外天气；
- 消费电子：笔记本电脑、电源适配器的过流保护，低功耗适配便携设备；
- 电力监控：小型智能电表、断路器的电流计量，隔离设计保障安全；
- 汽车电子：车载电源、小型电机（如座椅电机）的电流检测，-40℃~+125℃覆盖车载温区。
四、封装与可靠性设计
采用SOP-8标准贴片封装，尺寸紧凑（典型15.6mm×7.5mm），便于PCB自动化贴装，节省布局空间。单芯片集成所有功能模块，减少外围元件数量，降低系统故障点，提升长期可靠性。同时，封装采用耐高温材料，适配回流焊工艺，满足批量生产需求。
五、使用注意事项
- 电流回路连接：被测电流需串联在传感器的电流输入端（如1、8脚），注意极性与电流方向匹配（双向支持正负电流）；
- 供电要求：供电电压需稳定在3.3V±5%（3.135V~3.465V），避免过压损坏；
- 隔离布线：被测高压端与传感器输出端需保持1cm以上间距，避免电磁干扰；
- 过流防护：虽支持20A量程，但需避免长期过流（如25A以上），建议串联保险丝保护。
该产品凭借高性价比、集成度及宽适应性，成为中小功率电流检测场景的优选方案，可有效降低系统设计复杂度与成本。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Sourcing availability signal
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.
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.
