Allegro offers a unique solution for current sensing through the development of proprietary packaging that employs flip-chip technology. This technology generates excellent magnetic coupling in a core-less package design and provides up to 3000 VRMS galvanic isolation. The low-profile, small form factor packages are ideal for reducing PCB area over sense resistor op-amp or bulky current transformer configurations. The low resistance internal conductor allows for sensing up to 50 A continuous current. Allegro's fully integrated current sensor ICs are factory programmed at end of line testing to maximize device accuracy over temperature, and providing typical output error of 1%.
