APS11500: Two-Wire Hall-Effect Switch

APS11500设备是双线平面霍尔效应传感器集成电路（IC），根据ISO 26262：2011（待定评估）开发。它们包括支持功能安全的内部诊断。增强型的双线电流模式接口提供互连打开/短诊断，并添加安全状态，以传达诊断信息，同时保持与遗留双线系统的兼容性。双线传感器非常适合于安全应用，尤其是涉及长线线束的应用。亚博尊贵会员

APS11500产品选项包括磁性开关点，温度系数，滞后，以及器件是否响应北部或南部磁场（单极开关）或两者（双极锁存器或全峰开关）。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。

APS11500 sensors are engineered to operate in the 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.

The available SIP package with integrated discrete components (UC) enables PCB-less applications by incorporating all of the EMC protection components into the IC package. Other package options
include industry-standard surface-mount SOT (LH) and through-hole SIP (UA) packages. All three packages are RoHS-compliant and lead (Pb) free with 100% matte-tin-plated leadframes.

For situations where a functionally equivalent but factory-programmed two-wire latch or end-of-line programmable device is preferred, refer to the APS12400 and APS11900 device families, respectively.
