ACS70331 Description
The ACS70331 is Allegro’s first integrated, high sensitivity, current sensor IC for <5 A current sensing applications. It incorporates giant magneto-resistive (GMR) technology that is 25 times more sensitive than traditional Hall-effect sensors to sense the magnetic field generated by the current flowing through the low resistance, integrated primary conductor. The analog output provides a low noise high-speed...
