Overview

The DRV5056A4QDBZR is a high-performance, unipolar linear Hall effect sensor designed for precise magnetic field measurement. It provides an analog output voltage proportional to the magnetic flux density, featuring a 0.6V quiescent offset to simplify signal conditioning for unipolar north-pole sensing applications. With a 20kHz bandwidth and built-in temperature compensation, it is optimized for high-speed position and movement detection.

Why Choose This Part

This sensor offers a fast 20kHz bandwidth and a low-noise output, making it suitable for dynamic real-time applications. It includes integrated compensation for magnet temperature drift, ensuring stable accuracy across its full operating temperature range without external calibration.

Applications

Throttle and Pedal Position
Utilizing the unipolar linear output for accurate displacement sensing in automotive control systems.
Industrial Valve Monitoring
Providing non-contact position feedback for valve actuators in harsh industrial environments.
Liquid Level Sensing
Detecting the position of a float-mounted magnet to determine fluid levels in tanks.
Brushless DC Motor Feedback
High-bandwidth sensing for rotor position detection and commutation control.
