Uni Hall Click Board
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, the unipolar Hall switch aboard UNI HALL click 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.
The UNI HALL click 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.
