IC/Module: Melexis US5881 Unipolar Hall-Effect Switch
A unipolar Hall-effect switch, the CMOS-technology based Melexis US5881 integrates a voltage regulator, Hall sensor with dynamic offset cancellation system, Schmitt trigger and an open-drain output driver, all in a single package. It is a good choice for use in automotive and solid state switch applications.
Sensitive to North Pole Magnetic Field
Unlike BI HALL Click Board™, the unipolar Hall switch aboard UNI HALL Click Board™ only reacts to north pole magnetic fields, outputting a LOW logic level. In cases where the magnetic field is not strong enough, or of wrong polarity, the Click Board™ outputs a HIGH logic level through the mikroBUS INT line.
Communication Interface
The UNI HALL Click Board™ uses the mikroBUS INT line to communicate with your target board. It uses either a 3.3V or a 5V power supply, which is selectable via a solder jumper. The selection determines logic level voltage.
