A119x 和 A119x-F:可编程斩波稳定两线霍尔效应开关

Description

A119x 和 A119x-F 由一系列两线单极霍尔效应开关组成,可由用户在生产结束后预校,以优化磁性开关点在应用中的精度。后者(-F 选项)是温度补偿,用于铁氧体磁铁这些设备通过 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。

A119x 和 A119x-F 系列能满足许多汽车应用的需求。这些应用包括感应座椅调节导轨位置、安全带搭扣存在、引擎盖/后备箱锁闭和换挡选择器的位置。

与传统的开路集电极开关相比,两线单极开关在工作时少用一根线,所以它们非常适合对成本敏感的应用。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。

所有产品均以三种封装类型提供。LH 为 SOT-23W 微型扁平表面安装型封装。UA 是用于通孔安装的 3 引脚超微型单列直插式封装 (SIP)UB 是用于通孔安装的 2 引脚超微型单列直插式封装 (SIP),并集成了电源去耦电容器。所有三种封装均为无铅 (Pb) 封装,引脚框均采用 100% 雾锡电镀。
