Products Overview
The A31010 family of unipolar linear Hall-effect sensor ICs
Allegro MicroSystems
A31010 Small Low Power Unidirectional Linear Hall-Effect with Sleep Mode
A31010 Unidirectional Linear Hall-Effect Sensors. Provide a voltage output proportional to the applied magnetic field.
The A31010 family of unipolar linear Hall-effect sensor ICs is an ideal part for battery powered head-on (i.e. pushbutton) and slide-by (i.e. slider) motion detection present in game controller triggers, keyboards, security systems, liquid level, and other consumer applications.
The unipolar operation outputs a voltage proportional to the applied positive magnetic field ensuring maximum resolution while the external Vref pin provides flexibility for the output reference enabling operation in a ratiometric or non-ratiometric mode.
The fast wakeup and sleep time allows the A31010 to transition quickly between sleep and awake modes and the user-controlled sleep pin enables flexible duty cycles to optimize power consumption. These features, coupled with a low supply voltage rating down to 2.5 V, make this IC ideal for battery-powered applications while enabling easy integration to 3.3 V microcontrollers.
These devices are available in a small, lead free, 2 mm × 3 mm, 0.75 mm height DFN-6 package to minimize PCB board area.
