A1393SEHLT-T 是美国 ALLEGRO(埃戈罗)推出的一款高灵敏度模拟霍尔传感器,封装为 6 引脚 PowerWFDFN(6MLP/DFN)。器件以小巧封装提供精确的磁场到电压的线性转换,适用于空间受限且要求低功耗的磁感检测场合。典型特性为灵敏度 5 mV/Gs,工作电压范围 2.5V~3.5V,静态工作电流约 3.2 mA,工作温度 -20℃~+85℃。
说明:灵敏度 5 mV/Gs 意味着磁场变化 100 G 将引起约 500 mV 的输出摆幅,便于直接接入 ADC 采集。
6 引脚 DFN 封装体积小、热性能好。建议 PCB 设计时:
A1393SEHLT-T 适合追求高灵敏、低功耗及小封装的场合。若需更宽温度范围或不同灵敏度/输出特性,可参考 ALLEGRO 的同系列其他型号或联系供应商获取器件完整数据手册以确认详细电气特性和测试曲线。
如需我提供针对具体磁体、安装间隙或 MCU ADC 接入的电路示例与标定方法,可告知系统工作条件与目标磁体参数。

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.
