ACS781LLRTR-050U-T
Closed Loop/Open Loop Current Sensor AC/DC Current 3.3V 7-Pin PSOF T/R Automotive AEC-Q100
Allegro MicroSystemsThe ACS781LLRTR-050U-T by Allegro Microsystems is a high-precision, linear Hall-effect-based current sensor with 200 µΩ current conductor. Built in a new, core-less, low-profile, small-footprint package, the ACS781LLRTR-050U-T is rated for automotive use and can detect AC and DC currents up to 100A. The device operates on a single 3 to 3.6 V power supply, and features Allegro's proprietary shielding technology for industry-leading noise performance and reduced capacitive coupling to die due to high dV/dt signals.
