Discover Allegro's Advanced Magnetic Current Sensors!
Upgrade your designs with efficient, compact, and integrated solutions. Simplify your circuits and reduce component count with Allegro's innovative sensor technology.
Our ACS37041 and ACS37042 current sensors simplify current measurement with their compact SOT23-W package, eliminating the need for external shunt resistors and op-amps. These single-package, shuntless solutions reduce board space and component count, which makes them ideal for space-constrained applications. Including in cases where galvanic isolation up to 285 VRMS is required (ACS37042).
