Our family of fully integrated, high isolation current sensor solutions provides accurate measurement with very low resistance—all without the need for external isolation components.
Allegro's proprietary packaging uses flip-chip technology which generates excellent magnetic coupling in a core-less package design. Our solutions also provide up to 4800 VRMS galvanic isolation. These low-profile, small form factor packages are ideal for reducing PCB area over sense resistor op-amp or bulky current transformer configurations.
Automotive-Grade, Galvanically Isolated Current Sensor IC with Common-Mode Field Rejection and Overcurrent Detection in Small Footprint Low-Profile Packages
This application note will describe the use of the new high current ACS772 Hall-effect current sensor integrated circuit (IC) from Allegro MicroSystems and will give an overview of its features and improvements from previous Allegro high-current sensors.Learn More
Closed-loop current sensing technology is employed in many industrial and automotive applications for accurate current sensing. Allegro MicroSystems has developed magnetic-based current sensor IC solutions that achieve near closed-loop accuracy using an open-loop topology.Learn More
