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
