PACKAGE: Z 8-Pin TSSOP (LE) X Y Not to scale DESCRIPTION TheALS31313 3DMAG™ linear Hall-effect sensor IC provides a 12-bit digital value corresponding to the magnetic field measured in each of the X, Y, and Z axes.
The ALS31313 is preconfigured for use in 3D sensing applications for head-on linear motion, slide-by position sensing, and rotation angle measurements.
TheALS31313 is also offered in joystick mode, including a low gain option for the Z axis channel.
This feature enables the use of a back-bias magnet to provide return-to-zero force instead of traditional spring-based solutions.
Three different factory-programmed sensitivity ranges are available: ±500 G, ±1000 G, and ±2000 G.
The I2C address of the ALS31313 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 ALS31313 also includes 78 bits of user EEPROM.
Power management of the ALS31313 is highly configurable, allowing for system-level optimization of supply current and performance.
