CC6111TO是成都芯进(CrossChip)推出的高精度单极型霍尔效应开关,针对工业、汽车等对温度稳定性、弱磁检测要求严苛的场景设计。核心差异化在于采用斩波稳定技术,彻底解决普通霍尔开关的温漂问题,同时兼顾低功耗与宽电压适配,是替代传统机械开关或低精度霍尔的理想选择。
工作电压覆盖2.5V~28V,既能适配5V、12V、24V等常见工业/汽车电源,也能兼容2.5V低电压场景(如部分手持设备);工作电流仅2mA,静态功耗极低,适合电池供电的便携设备或对功耗敏感的系统,无需额外散热设计。
工作点(Gs)仅4mT,释放点3mT,属于低磁敏霍尔开关——对弱磁场(如小磁体、远距离磁信号)检测灵敏度高,能替代部分需要强磁体的方案,降低系统成本;同时工作点与释放点差值小(1mT),开关响应一致性好,避免误触发。
工作温度范围达**-40℃+150℃**,远超普通霍尔开关的0℃85℃范围,可直接应用于汽车发动机舱(温度可达120℃以上)、工业户外设备(低温环境)等 harsh 环境,无需额外温度补偿电路。
这是CC6111TO的核心亮点:通过斩波调制抵消器件内部的失调电压漂移,彻底解决温度变化、电源波动带来的性能偏差,实现低温漂(通常<±0.5mT/℃)——普通霍尔开关温漂可能达±2mT/℃以上,而CC6111TO在全温区工作点基本保持恒定,适合医疗设备等对精度要求极高的场景。
CC6111TO的参数特性使其适配多领域:
采用TO-92S直插封装,体积小(φ4.5mm×10.5mm)、安装方便,支持手工焊接或自动化插件;封装材料耐温、抗冲击,配合宽温区设计,可靠性达到工业级标准——经过高低温循环、老化测试、EMC电磁兼容测试,能应对复杂电磁环境(如汽车点火干扰、工业变频器噪声)。
由成都芯进电子(CrossChip) 研发生产,该公司专注霍尔传感器10余年,在斩波稳定技术、低温漂霍尔设计上积累了成熟经验;CC6111TO已通过RoHS环保认证,符合汽车级/工业级可靠性要求,是国内少数能替代进口高精度霍尔的产品之一。

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.
