SS441A
Overview
The SS441A is a high-sensitivity unipolar Hall effect digital switch designed for reliable magnetic sensing in industrial and automotive environments. It operates across a wide supply voltage range of 3.8V to 30V and provides a temperature-compensated open-collector output that sinks up to 20mA. The sensor features a quad Hall IC design to minimize the effects of mechanical stress on the package.
Why Choose This Part
The SS441A offers superior thermal stability through built-in temperature compensation, ensuring consistent 11.5mT trip and 2mT release points from -40 to 150 degrees Celsius. Its open-collector output simplifies interfacing with various logic levels, while the quad-element design provides high resistance to physical stress and vibration.
Applications
Key Specifications
Getting Started
To integrate the SS441A, connect a pull-up resistor between the open-collector output pin and the logic supply voltage (Vcc). Ensure the south pole of the magnet faces the branded side of the TO-92 package to trigger the switch. For prototyping, the 0.1-inch lead spacing allows for easy insertion into standard breadboards or perfboards.
