Product Overview

The A31301 is a flexible three-axis Hall-effect sensor IC designed for precise magnetic flux density measurement across one, two, or three axes, and for calculating angles in user-defined planes. Available in three field configurations (600 G, 1400 G, 2000 G) and preconfigured for SPI or I2C interfaces, it offers customer-programmable magnetic temperature coefficients with a factory default for neodymium magnets. Supporting high-speed SPI (up to 10 MHz) and I2C (up to 1 MHz) with flexible addressing options, the A31301 is ideal for battery-operated applications due to its low leakage sleep current and configurable power management. Its compact 3 mm 3 mm DFN package makes it suitable for space-constrained designs.
