US5881ESE-AAA-000-RE
Overview
The US5881ESE-AAA-000-RE is a unipolar Hall-effect switch designed in CMOS technology for high-reliability magnetic sensing. It features a chopper-stabilized amplifier stage to minimize offset and provides an open-drain output that simplifies interfacing with various logic levels. This sensor operates over a wide supply voltage range from 3.5V to 24V, making it suitable for both industrial and battery-powered systems.
Why Choose This Part
The component utilizes a chopper-stabilized architecture which ensures stable magnetic switching points across its operating temperature range of -40 to 85 degrees Celsius. Its open-drain output supports up to 50mA, allowing it to drive small relays or LEDs directly without additional buffering. Furthermore, the low typical current consumption of 2.5mA aids in energy-efficient designs.
Applications
Key Specifications
Getting Started
To use this sensor, connect a pull-up resistor (typically 4.7k to 10k ohms) between the output pin and your logic supply voltage. Ensure a decoupling capacitor is placed close to the VDD pin to filter supply noise, especially in automotive or industrial environments. Since this is a unipolar switch, ensure the South pole of your magnet is oriented toward the branded side of the TSOT-23 package for correct activation.
