Cảm biến công tắc và chốt từ tính Hall siêu tiết kiệm năng lượng

Allegro MicroSystems Micropower Magnetic Hall Switch (APS11753) and Latch (APS12753) Sensors are AEC-Q100 qualified for low-voltage applications. These sensors are temperature-stable and suited for operation over extended junction temperature ranges up to +165°C. These Hall-effect switches/latches provide contactless control of a push-pull output, which actuates in response to a magnetic field applied to the branded package face. Additionally, the micropower logic allows ultra-low power consumption and operation from 2.2V to 5.5V. Equipped with chopper stabilization, the Allegro MicroSystems components reduce the residual offset normally caused by device overmolding, temperature dependencies, and thermal stress, allowing superior high-temperature performance. The lead-free and RoHS-compliant APS11753 and APS12753 ICs are offered in package type MD-3, a standard 3-pin SOT23-3 surface-mount package.
