ACS37800 AC/DC Power Monitoring Current Sensor ICs

Allegro MicroSystems ACS37800 Programmable AC/DC Power Monitoring Current Sensor ICs offer integrated current sensor technology that leverages the Hall effect and galvanic isolation to deliver reinforced isolation without extra board space. Multiple power supplies and digital isolation ICs are not required when powered from the same supply as the microcontroller unit, reducing the size of the printed circuit board (PCB).
