Allegro MicroSystems A31010 Unidirectional Linear Hall-Effect Sensors

Allegro MicroSystems A31010 Unidirectional Linear Hall-Effect Sensors provide a voltage output proportional to the applied magnetic field. The A31010 features a user-controlled sleep pin and a rapid wake-up time that allows minimal power consumption and provides magnetic data quickly after waking up. These features, coupled with a low supply voltage rating of 2.5V and non-ratiometric output, make the IC ideal for battery-powered applications.

Features

User-controlled sleep mode with fast (<60µs) wakeup time for lag-free power savings
3.2mA active and 25µA sleep current reduces total power consumption and extends battery life
Operates down to 2.5V supply for battery applications

Low quiescent voltage output (QVO) maximizes output range and resolution at ADC input
Ambient temperature range from –20°C to +85°C, suited for personal electronics and gaming applications

Applications

Game controllers
Joysticks
Triggers
Personal electronics

Keyboards
Virtual and augmented reality devices
