APS12400：双线霍尔效应闩锁

APS12400 devices are two-wire planar Hall-effect sensor integrated circuits (ICs) that include internal diagnostics and support functional safety. The enhanced two-wire current-mode interface provides interconnect open/short diagnostics and adds a Safe State to communicate diagnostic information while maintaining compatibility with legacy two-wire systems. Two-wire sensors are well-suited to safety applications, especially those involving long wire harnesses.

APS12400是一种工厂校准的闩锁（双极开关），可提供多种产品选项，包括磁性开关点，温度系数和输出极性。响应可以与SMCO，NDFEB或低成本铁氧体磁铁匹配。选择两个输出电流电平和输出极性。

APS12400传感器设计经营的harshest environments with minimal external components. They are qualified beyond the requirements of AEC-Q100 Grade 0 and will survive extended operation at 175°C junction temperature. These monolithic ICs include on-chip reverse-battery protection, overvoltage protection (40 V load dump), ESD protection, overtemperature detection, and an internal voltage regulator for operation directly from an automotive battery bus. These integrated features reduce the end-product bill of materials (BOM) and assembly cost.

具有集成离散组件（UC）的可用SIP封装通过将所有EMC保护组件结合到IC包中，使PCB的应用程序能够实现PCB的应用程序。亚博尊贵会员其他封装选项包括行业标准的表面贴装SOT（LH）和压电池SIP（UA）封装。所有三个包装都是RoHS兼容和引线（PB），带有100％哑光镀锡引线框架。

对于功能等同物但工厂编程的双线锁存器或线端可编程设备的情况，分别是指APS12400和APS11900设备系列的情况。
