Introduction

The principle of the hall sensor 3144 is the Hall Effect, when the current is perpendicular to the magnetic field through the conductor, a electric field will be generate at the direct of being perpendicular to current and magnetic field. The hall sensor output low and turns on when a magnetic field is perpendicular to the hall sensor exceeds the threshold. When the magnetic field disappeared, the hall sensor output high.
