Description

Allegro A1101-A1104 和 A1106 型霍尔效应开关是深受欢迎的 Allegro 312x 和 314x 系列单极开关的下一代替代品。A110x 系列采用 BiCMOS 技术生产，包含以快速通电和低噪音操作为特色的器件。器件编程在封装之后进行，以消除封装应力引起的偏置，确保更高的开关点精确度。独一无二的霍尔元件几何尺寸以及低偏移放大器有助于最大限度减少噪声，和减少通常由器件超模压、温度剧增和热应力引起的残余偏移电压。

Allegro A1101-A1104 和 A1106 霍尔效应开关将以下元件包含在单硅片上：稳压器、霍尔电压发生器、小型信号放大器、施密特触发器和 NMOS 输出晶体管。集成稳压器允许在 3.8 至 24 V 之间工作。丰富板载保护电路可以经受 ±30 V 的绝对最大电压额定值，无需添加外部元件就可为汽车和电动机整流应用提供超级保护。除了磁性开关点以外，该系列的所有器件完全相同。

BiCMOS 小巧的几何尺寸让这些器件均能采用超小型封装。现有的封装类型可为大多数应用提供磁性最优化的解决方案。封装 LH 是 SOT23W 微型扁平表面安装型封装，而封装 UA 是供通孔安装使用的三引脚超小型 SIP。所有封装均不含铅，引脚框采用 100% 雾锡电镀。
