00 — Overview

What the HAL3144 does

The HAL3144E is a single-axis Hall-effect magnetic sensor designed to detect magnetic field strength along one axis. This device operates across a supply voltage range of 2.7 to 5.5 V and features a typical sensitivity of 3.5 mV/G. It includes an integrated temperature compensation circuit to maintain accuracy over a wide operating temperature span from -40 to +85 degrees Celsius. The output voltage shifts linearly with the applied magnetic field, providing a clear signal for position or speed detection. Engineers typically use this component in applications requiring precise magnetic field measurement, such as brushless motor control, current sensing, and proximity detection systems where reliable data is critical.
