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 ICC  
□ 12 µA to 2 mA ICC (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  
Continued on next page...  
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)
