  • Product introduction

A1150、A1152、A1153、A1155、A1156、A1157 和 A1158 是双线单极霍尔效应开关系列,经过厂方调整具有最高的磁性开关点准确度。这些设备通过 Allegro®先进的 BiCMOS 晶圆制造流程,使用其专有的高频率四相斩波稳定技术制造。此技术可实现相对于所有操作温度的磁稳定性,消除单霍尔元件装置的固有偏移,适用于恶劣的应用环境。

A115x 系列有多种汽车应用。包括感应座椅轨道位置、座椅带扣存在、引擎盖/行李箱锁闭以及换档选择器位置。

because双线单极开关比传统的开路集电极开关少用一根线,因此双线单极开关尤其适用于对成本敏感的应用。而且,系统设计师能始终获得诊断信息,因为输出电流必须始终在两个狭窄范围内。任何不在这两个范围内的电流水平则表明出现故障。

所有产品均以两种封装类型提供。LH 是供表面安装应用使用的 SOT-23W 微型低厚度封装。UA 是供过孔安装使用的三引脚超小型单列直插式封装 (SIP)。两种封装均为无铅封装,采用 100% 雾锡镀层引脚框。


  • 高速四相斩波稳定
  • 相对于温度范围的低开关点漂移
  • 对热应力和机械应力的低敏感度
  • 芯片保护
    • 电源瞬态保护
    • Reverse battery protection
    • 板载稳压器
    • 3.0 到 24 V 工作电压
  • Solid-state reliability
  • 稳健的 EMC 和 ESD 性能
  • 使用专有的 40-V 夹紧结构,实现行业领先的 ISO 7637-2 性能
