ACS780KLRTR-150B-T

The ACS780KLRTR-150B-T is a high-current, galvanically isolated Hall-effect current sensor from Allegro Microsystems. It measures bidirectional DC and low-frequency AC current by routing the primary conductor through the package, with a ratiometric analog output proportional to the sensed current. The “±150 A” (150B) full-scale range indicates its maximum measurable current. It operates from a single 3.3–5 V supply and provides isolation between the high-current path and the logic/output side, allowing safe interfacing to microcontrollers. The bandwidth is suitable for detecting fast transients (tens of kHz), and the device is packaged in a tape-and-reel (KLRTR) format for automated assembly. Typical applications include motor drives, power supplies, battery management, and other systems requiring safe, isolated current measurement.
