APS11203/APS12203 Hall Effect Switch Sensors

Allegro MicroSystems APS11203/APS12203 Hall effect switch sensors are AEC-Q100 qualified for high-voltage automotive and industrial applications. These ICs are temperature-stable and offer precision performance over an extended junction temperature range up to +165°C. This family of Hall effect switches provides contactless sensing of magnetic fields and an open drain output that actuates in response to the detected filed strength at the branded package face. A wide range of available models allows for the selection of devices capable of responding to magnetic fields of both north and south polarity, and varying field strengths. In addition, the APS11203/APS12203 is designed to maximize system robustness with features that include reverse-battery protection, an output current limiter, and overvoltage protection.
