CT8132EK-HS3 产品概述
一、产品简介
CT8132EK-HS3 是 ALLEGRO 推出的全极型数字磁开关级器件，采用 TMR（磁隧道结）技术，针对板级接口与磁感检测场景优化设计。器件在宽电压与高温工况下保持稳定工作，响应可靠、功耗极低，适合对尺寸与功耗有严格要求的嵌入式和工业应用。
二、主要性能指标
- 类型：全极型（Omnipolar）数字磁开关
- 工作电压：1.7 V ～ 5.5 V
- 静态工作电流：约 190 nA（典型）
- 采样频率：10 Hz
- 输出形式：推挽（Push-Pull），无须外拉电阻
- 最大输出电流：3 mA（驱动能力）
- 工作点（吸合 Gs）：≈ 7 mT
- 释放点（释放 Gh）：≈ 5 mT
- 工作温度范围：-40 ℃ ～ +125 ℃
- 封装：SOT-23-3（板上安装）
注：器件以指定的磁场门限为动作基准，实际吸合/释放距离受磁铁尺寸、极性及安装间距影响，应在系统设计时以实测为准。
三、封装与引脚
SOT-23-3 紧凑封装，三引脚布局适配常见 PCB 布线规范。典型引脚功能为 VCC、GND 与 OUT（推挽输出）。建议在 VCC 引脚附近放置 0.1 μF 陶瓷旁路电容以抑制供电噪声，靠近器件焊盘布地平面与短回流路径以提高抗干扰性能。
四、典型应用场景
- 板级开关/盖体检测、位置与限位检测
- 小型电机转速/相位检测（低速场合）
- 便携与电池供电设备的接近/状态检测
- 工业与汽车电子的高温环境传感（非安全关键总线）
- 替代机械微动开关用于寿命与可靠性要求较高的场合
五、使用要点与建议
- 由于为全极型器件，对任一极性磁场均有响应；若仅需单极响应，需配合磁路或屏蔽设计。
- 封装对磁场方向与距离敏感，建议在设计初期通过实测确定最佳磁铁位置与行程裕度。
- 输出为推挽，能够直接驱动小电流负载；若驱动较大负载或长线，请评估开关损耗与热量。
- 高温环境下长期应用需考虑 PCB 材料及周边元件的温漂影响。
CT8132EK-HS3 以其低功耗、宽电压与高温适应能力，适合对尺寸与可靠性有要求的现代电子产品，提供稳定的磁场开关功能。

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.
