The ACS7xx Current Sensor familes are innovative, monolithic, isolated Hall-Effect based current sensors in industry leading small sized packages. Power dissipation of the sensors is typically 2 to 3 orders of magnitude less than sense resistor solutions, and unlike current transformers the sensors can measure DC current. All of Allegro's current sensors run from a single, +5V supply, are lead-free compliant, and are safety certified by TUV America.
