Overview

The AH4931Q-W6-7 is an AEC-Q100 qualified 3D Hall effect sensor designed for linear magnetic field measurement across X, Y, and Z axes. It provides 12-bit digital output via a high-speed 1MHz I2C interface, supporting a wide sensing range of +/-130mT. This automotive-grade sensor is optimized for low power consumption, featuring a shutdown current as low as 9nA and a low-power 10Hz operating mode.

Why Choose This Part

This sensor offers exceptional power flexibility with a 9nA shutdown current and integrated interrupt signaling to wake up host microcontrollers only when needed. Its AEC-Q100 qualification and wide operating temperature range of -40degC to 125degC make it suitable for harsh automotive environments. The 12-bit resolution per axis ensures high-fidelity position tracking within a compact SOT-26 package.

Getting Started

Interface the AH4931Q with any I2C-capable microcontroller operating between 2.8V and 5.5V. Use the INT pin to implement interrupt-driven workflows that keep the MCU in sleep mode until a magnetic threshold or measurement completion is reached. For initial prototyping, ensure the I2C bus is configured for Standard, Fast, or High-Speed mode up to 1MHz.
