### 物料型号 - 型号：ATS137ATC

### 器件简介 - ATS137是一款霍尔效应开关IC，用于无接触式开关应用。该器件包括一个用于磁感应的芯片霍尔电压发生器、一个放大霍尔电压的放大器、一个提供开关滞后以抑制噪声的施密特触发器，以及一个开路集电极输出。带隙稳压器允许其在宽电压范围内工作。

### 引脚分配 - Vcc (Pin 1)：正电源 - Vss (Pin 2)：地 - DO (Pin 3)：数字输出

### 参数特性 - 供电电压：3.5V至20V - 反向极性保护电压：-20V - 磁通密度：无限制 - 输出关闭电压：30V - 连续“开”电流：25mA - 工作温度范围：-20°C至85°C - 存储温度范围：-65°C至150°C - 最大结温：175°C

### 功能详解 - ATS137能够将磁通量变化转换为数字输出信号，实现从磁系统到电系统的接口。输出驱动器为开路集电极拓扑结构，最大汇流能力为25mA。当磁通量大于操作点(Bop)时，输出(Vo)将变为低电平(打开)，当磁通量移除且低于释放点(Brp)时，输出将关闭。相关的波形图如图3所示。

### 应用信息 - 主要应用：VCD/DVD装载机、CD/DVD ROM的托盘开闭检测、手机后盖检测、冰箱门检测、微波炉门传感器等家用安全设备。由于其无接触且无机械接触点，其可靠性和寿命远高于簧片继电器，且开关速度远快于机械装置。

### 封装信息 - 封装类型：SOT23-3L - 尺寸：详细尺寸信息已在PDF文档中提供，包括最小、标称和最大尺寸，单位为毫米和英寸。
