A1101ELHLT-T
Overview
The A1101ELHLT-T is a continuous-time unipolar Hall-effect switch designed for reliable magnetic sensing in demanding environments. It features a South pole sensitive open-drain output and is AEC-Q100 qualified for automotive applications. The device operates across a wide 3.8V to 24V supply range and maintains stable switching points despite temperature fluctuations.
Why Choose This Part
This sensor offers high reliability with integrated reverse battery protection and robust EMC performance. Its AEC-Q100 qualification and wide operating temperature range of -40C to 85C make it suitable for harsh automotive and industrial deployments. The continuous-time architecture ensures fast power-on times and low noise compared to chopped-stabilized alternatives.
Applications
Key Specifications
Getting Started
To implement the A1101ELHLT-T, connect a pull-up resistor between the open-drain output pin and your logic voltage (up to 24V). Place a 0.1uF ceramic bypass capacitor close to the VDD pin to improve noise immunity, though the device is designed for stability even without one. Ensure the South pole of your magnet faces the branded side of the SOT-23W package to trigger the 17.5mT trip point.
