The ACS725LLCTR-50AB-T is an automotive-grade, galvanically isolated current sensor IC designed for accurate AC or DC current sensing in space-constrained applications. It features a small-footprint SOIC8 package with a 1.2 mΩ primary conductor resistance for low power loss and high inrush current withstand capability. The device operates on a single 3.3 V supply and provides a ratiometric analog output proportional to current, with a sensitivity of 26.4 mV/A for a ±50 A measurement range. Integrated differential Hall sensing rejects common-mode magnetic fields, and an on-chip shield suppresses output noise from high dV/dt transients. It is AEC-Q100 qualified, operates from -40°C to 150°C, and is manufactured with Pb-based solder bumps for RoHS compliance under permitted exemptions. The filter pin allows bandwidth tailoring for improved resolution at lower frequencies.
