ALS31300

3-D Linear Hall-Effect Sensor with I²C Output

and Advanced Low Power Management

FEATURES AND BENEFITS

DESCRIPTION

• X- and Y-axis sensing of joystick position

TheALS31300three-axislinearHall-effectsensorICprovides

• Z-axis sensing of “crouch” or push button motion

• Capable of operating with back-bias magnets for joystick

return-to-zero

a 12-bit digital value corresponding to the magnetic field

measured in each of the X, Y, and Z axes. The ALS31300 is

preconfigured for use in 3D sensing applications for head-on

linear motion, slide-by position sensing, and rotation angle

measurements.TheALS31300isalsoofferedinjoystickmode,

including a low gain option for the Z axis channel. This feature

enablestheuseofaback-biasmagnettoprovidereturn-to-zero

force instead of traditional spring-based solutions.

• Ideal for battery-powered, low-voltage applications

□ 2.65 to 3.5 V single supply operation

□ 1 MHz I²C compatibility down to 1.8 V

□ 14 nA (typ) Sleep I_CC

□ 12 µA to 2 mA I_CC(typ) in low-power duty cycle mode

• Industry standard I²C interface for easy system integration

□ Up to 1 MHz (Fast Mode+) I²C communication

□ 16 selectable addresses via external resistor divider

□ 127 available address configurable via EEPROM

• On-chip EEPROM

Three different factory-programmed sensitivity ranges are

available: ±500 G, ±1000 G, and ±2000 G.

The I²C address of theALS31300 can be set either by external

resistors (16 unique addresses) or programmed into EEPROM

via I²C (127 unique addresses), allowing for multiple devices

on the same bus. The ALS31300 also includes 78 bits of user

EEPROM.

□ Stores factory- and user-configured settings

□ 78 bits of user EEPROM for additional storage

□ On-chip charge pump for easy programming

Power management of the ALS31300 is highly configurable,

allowing for system-level optimization of supply current and

performance. Sleep mode consumes just 14 nA (typical),

makingtheALS31300wellsuitedforportable,battery-operated

applications.

PACKAGE: 10-Contact DFN (EJ)

Pin 1

The ALS31300 is supplied in a 3 mm × 3 mm × 0.8 mm,

10-contact DFN package (“EJ”). This small footprint package

is lead (Pb) free, with 100 % matte-tin leadframe plating.
