Overview

The SLSS49E-3 is a high-performance linear Hall effect sensor designed to provide a proportional analog voltage output based on magnetic flux density. Operating from 3V to 12V, this SOT-23 device offers high ESD protection up to 4kV and a wide temperature range of -40C to 150C, making it suitable for demanding industrial and automotive environments.

Why Choose This Part

This sensor offers a high sensitivity of 2.95 to 3.55 mV/G and is capable of measuring magnetic fields up to 460 Gauss. Its miniature SOT-23 construction allows for high-density PCB layouts, while the low-noise output ensures precision in analog control loops.

Applications

Current Sensing
Monitoring DC and AC currents in power supplies and battery management systems by detecting the magnetic field around a conductor.
Motor Control
Providing feedback for brushless DC motor commutation and speed control through magnetic pole detection.
Position Sensing
Detecting linear or rotary movement in industrial actuators and automotive throttle or pedal assemblies.
Ferrous Metal Detection
Used in proximity switches to detect the presence or movement of iron-based components.

Getting Started

To evaluate the SLSS49E-3, connect the VDD pin to a stable 5V supply and monitor the output pin with a high-impedance 12-bit ADC to match its native resolution. Use a bypass capacitor close to the supply pins to minimize noise in high-current motor environments.
