Overview

The TMAG5273C1QDBVR is a low-power linear 3D Hall-effect sensor designed for high-precision magnetic field measurements across the X, Y, and Z axes. It features an integrated I2C interface supporting up to 1MHz clock speeds and includes an on-chip CORDIC engine for angle calculations with gain and offset adjustment. Operating from a supply voltage of 1.7V to 3.6V, this sensor is optimized for position sensing and human-machine interface applications.

Why Choose This Part

This sensor offers extreme power efficiency with a standby current as low as 0.45uA and a sleep mode of 1uA, making it ideal for battery-operated devices. It simplifies firmware development by performing complex angle calculations on-chip and supports high-speed data acquisition with a 20kSPS single-axis conversion rate.

Applications

Rotary and Linear Position Sensing
Utilizes the 3D magnetic sensing and integrated CORDIC engine to track magnet rotation or linear displacement in robotics and industrial actuators.
Human-Machine Interface (HMI)
Enables non-contact control knobs, joysticks, and sliders in automotive interiors and consumer appliances.
Tamper Detection
Detects external magnetic interference in smart meters and security systems using configurable magnetic thresholds.
Proximity and Door Sensing
High-sensitivity detection of door or lid closure for low-power IoT devices and smart home security.
