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

DESCRIPTION
The A31010 family of linear Hall-effect sensor ICs provides a
voltage output that is proportional to the applied magnetic field.
The user-controlled sleep pin and rapid wakeup time allows
the A31010 to consume minimal power and provide magnetic
data quickly after waking up. These features coupled with a
low supply voltage rating of 2.5 V and non-ratiometric output
make this IC ideal for battery-powered applications.
Many human machine interface (HMI) applications such as
gaming controller joysticks, triggers, and keyboards will benefit
from the sensor’s unidirectional output.
These devices are available in a small 2 mm×3 mm, 0.75 mm
nominal height micro-leaded package (MLP/DFN). It is lead
(Pb) free with 100% matte tin leadframe plating
APPLICATIONS
• Game controllers
