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.
Allegro's ACS37002 is a 400 kHz, high accuracy current sensor with pin-selectable gains and adjustable overcurrent fast fault with high isolation, offered in SOIC16W package options.
The Allegro ACS724/ACS725 family of current sensor ICs are economical and precise solutions for AC or DC current sensing in industrial, automotive, consumer, and communications systems
