AH1912-W-7 产品概述

一、产品简介

AH1912-W-7 是 DIODES(美台)推出的一款全极型线性霍尔传感器,封装为 SC-59。器件在 1.6V 至 5.5V 的宽电压范围内工作,具备对正负极磁场的响应能力,既能用于双向接近/开关检测,也适合做低功耗的线性磁场测量。器件工作电流极低,仅约 1.6 µA,适合电池供电和能量受限的便携式系统。

二、主要性能特点

  • 全极型(双向)响应:可同时检测 N、S 两极磁场,便于无极性安装与设计。
  • 宽工作电压:1.6V ~ 5.5V,兼容多种单电源系统。
  • 低功耗:典型工作电流 1.6 µA,适合超低功耗应用。
  • 明确磁阈:工作点(Operate)±4.2 mT,释放点(Release)±3.3 mT,具有约 0.9 mT 的滞后,利于抗干扰与稳定切换。
  • 宽温度范围:-40 ℃ ~ +85 ℃,满足工业级环境要求。

三、主要技术参数(概要)

  • 类型:全极型(线性霍尔)
  • 工作电压:1.6 V ~ 5.5 V
  • 工作点(Gs, Operate):±4.2 mT
  • 释放点(Gs, Release):±3.3 mT
  • 工作电流:约 1.6 µA(典型值)
  • 工作温度:-40 ℃ ~ +85 ℃
  • 封装:SC-59

(注:更详细的电气特性、输出类型及典型曲线请参考原厂数据手册。)

四、封装与机械特性

AH1912-W-7 采用 SC-59 小封装,占板面积小、适合空间受限的布局。SC-59 常用于表面贴装的霍尔传感器,便于自动贴装与回流焊接。建议在布局时预留合适的过孔/散热空间,并参考数据手册确认引脚排列与尺寸公差。

五、典型应用场景

  • 便携式与电池供电设备的接近/位置检测(门磁、盖位检测等);
  • 微型电机或风扇的转子位置检测;
  • 磁编码与非接触式行程检测;
  • 低功耗人体/物体检知与开关替代;
  • 工业控制中需要耐环境变化的磁场检测。

六、使用与设计建议

  • 磁场设计:选用磁体并且确定工作距离时,请根据器件的工作/释放点(±4.2 mT / ±3.3 mT)选择合适的磁铁和间距,保证在目标位置磁场强度能稳定越过工作点并低于释放点以产生可靠切换。
  • 去耦与电源:即便工作电流极低,仍建议靠近电源引脚放置 0.01 µF ~ 0.1 µF 的去耦电容以抑制瞬态与噪声,保证输出稳定。
  • 布局注意:避免强电流回路或高频线靠近传感器引脚,减小磁/电干扰。若需测量微小磁变化,应远离大电流导体。
  • 热管理:工作温度范围宽,但长期高温会影响偏置与灵敏度,重要应用建议做温度校准或补偿。
  • 引脚与输出:器件具体引脚排列、输出类型(推挽/开漏/模拟)以及绝对最大额定值请以厂家数据手册为准,设计前务必核对确认。

总结:AH1912-W-7 以其全极响应、超低功耗与宽电压特性,适合在对空间、电能和环境适应性要求较高的场合做可靠的磁场检测与位置感知。在设计中关注磁场强度匹配与电磁兼容,配合数据手册进行可靠性验证,可发挥器件最佳性能。

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
