SL1713SH单极型霍尔传感器产品概述

SL1713SH是Slkor(萨科微) 推出的一款高性能单极型霍尔传感器,针对低功耗、宽电压适配及宽温环境下的位置/磁场检测需求优化设计,广泛适用于消费电子、工业控制、智能家居等领域的小型化集成场景。

一、产品核心定位与关键特性

该传感器聚焦**“低功耗+高兼容性+稳定磁响应”** 三大核心方向,核心特性如下:

  • 低功耗设计:典型工作电流仅900nA,支持电池供电设备长续航;
  • 宽电压范围:1.8V~5.5V输入,适配主流MCU及电源系统;
  • 稳定磁学性能:单极型触发,工作点(Gs)5mT、释放点3.5mT,磁响应一致性好;
  • 宽温可靠性:工作温度覆盖-40℃~+85℃,满足极端环境应用;
  • 推挽输出:无需外接上拉电阻,直接兼容TTL/CMOS逻辑电平,简化电路设计。

二、基础参数详细说明

1. 电气参数

  • 工作电压:1.8V~5.5V,可兼容低功耗MCU(如1.8V供电的STM32L系列)及常见5V电源系统,无需额外电源转换电路;
  • 工作电流:典型值900nA,远低于同类产品平均水平,特别适合无线传感器、智能门锁等电池供电场景,显著延长续航时间;
  • 输出类型:推挽输出,高电平接近电源电压,低电平接近地,驱动能力稳定,可直接驱动LED或逻辑门电路。

2. 磁学参数

  • 类型:单极型霍尔传感器(仅对N极磁场敏感,磁场强度达到工作点时输出触发);
  • 工作点:5mT(磁场强度≥5mT时,传感器输出切换);
  • 释放点:3.5mT(磁场强度≤3.5mT时,传感器恢复初始输出);
  • 采样频率:25Hz,适合中等频率的位置检测(如电机转速、物体移动监测)。

3. 环境与封装参数

  • 工作温度:-40℃~+85℃,可适应户外低温、工业车间高温等环境;
  • 封装:SOT-23-3L(3引脚表面贴装),尺寸约2.9×1.6×1.0mm,占板面积小,支持自动化贴装,适合紧凑型产品设计。

三、典型应用场景

SL1713SH因体积小、功耗低、性能稳定,广泛应用于以下场景:

  1. 智能家居:智能门锁门磁检测(判断门的开关状态)、窗帘电机位置检测;
  2. 消费电子:无线耳机充电盒盖检测、智能手表表带扣状态检测、小家电(榨汁机、电风扇)电机转速监测;
  3. 工业控制:流水线物体位置检测、小型电机霍尔编码器、工业传感器的位置感应;
  4. 汽车电子:车载小电器(如点烟器、座椅调节)的位置检测(注:需结合汽车级认证,但参数已覆盖车载环境温度范围)。

四、产品性能优势对比

与同类单极型霍尔传感器相比,SL1713SH的优势突出:

  • 功耗优势:900nA工作电流比同类产品低30%以上,电池供电设备续航提升明显;
  • 电压兼容性:1.8V~5.5V宽范围,无需针对不同电源系统做电路调整;
  • 磁响应一致性:工作/释放点偏差小(典型±0.5mT),避免误触发或检测失效;
  • 集成便利性:SOT-23-3L封装仅3引脚,电路设计简单(电源、地、输出),降低PCB布局难度。

五、应用设计注意事项

为确保传感器稳定工作,设计时需注意:

  1. 电源去耦:在电源引脚(VCC)与地(GND)之间并联0.1μF陶瓷电容,滤除高频噪声;
  2. 磁源匹配:选择N极磁体,确保检测位置的磁场强度≥5mT(工作点),远离时≤3.5mT(释放点),避免磁场过弱导致检测失效;
  3. 抗干扰设计:远离强电磁干扰源(如电机、高频变压器),必要时增加屏蔽层;
  4. 温度补偿:极端温度(如-40℃或+85℃)下,可适当调整磁体强度(如更换稍强磁体),确保磁场仍在工作/释放点范围内。

SL1713SH凭借低功耗、宽适配、高可靠的特性,为各类位置/磁场检测场景提供了经济高效的解决方案,是小型化、电池供电设备的理想选择。

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.

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
