JSM464 产品概述
一、产品简介
JSM464 是杰盛微（JSMSEMI）推出的一款全极型低功耗霍尔开关器件。器件在 2.5V～5.5V 的电源范围内稳定工作，适合电池供电与系统级电源设计。典型工作点 (Gs) 为 2.7 mT，释放点 (Gs) 为 1.5 mT，响应灵敏且具有明确的磁滞特性，便于实现抗抖与可靠开关动作。工作温度范围为 -40℃～+85℃，可满足工业级环境要求。
二、主要特性
- 类型：全极型（可对北/南极磁场响应）
- 工作电压：2.5V ～ 5.5V
- 工作点 (Gs)：2.7 mT；释放点：1.5 mT
- 工作电流：典型 50 μA（超低静态功耗，适合能源受限系统）
- 工作温度：-40℃ ～ +85℃
- 封装：SOT-23 表面贴装，体积小、便于自动化贴片与高密度布局
三、引脚与封装
JSM464 提供 SOT-23 小外形封装，典型为三引脚配置（VCC、GND、OUT）。封装利于空间受限的应用场景与成本敏感型设计。具体引脚定义与焊盘尺寸请参照官方数据手册以保证机械与电气兼容。
四、典型应用
- 无刷/有刷电机角度/位置检测与转速感应
- 笔记本盖、手机翻盖、门禁与盖位检测
- 无线遥控与便携传感器的低功耗唤醒电路
- 车用车门/座椅位置检测（在符合温度与EMC要求下）
- 工业自动化中的限位与接近开关
五、设计与使用建议
- 电源去耦：在 VCC 与 GND 之间靠近器件放置 0.1 μF 陶瓷电容以抑制电源噪声。
- 输出接口：若用于直接连接 MCU，请确认输出类型（推挽或漏极开路）；若为漏极开路，请外接合适上拉电阻（典型 10 kΩ）。
- 磁体选型与定位：根据工作点选择磁体强度与极性，保持稳定的磁路方向与合理间距以获得重复性好的切换动作。
- 布局注意：避免大电流回流路径靠近霍尔芯片，减小寄生磁场与温度漂移影响。对高精度场合建议做温度与线性校准。
六、可靠性与支持
JSM464 以低功耗、全极响应与工业级温度范围为设计出发点，适用于多种消费与工业产品。客制化参数、批量采购与技术支持请联系 JSMSEMI 或授权代理，获取完整数据手册、器件曲线与样品测试报告。
Request for quote
Send RFQ
Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
