ACS37220 Current Sensor Compact Carriers

These compact carriers house Hall‑effect current sensors that provide galvanic isolation and an ultra‑low resistance path, minimising voltage drop in high‑current circuits. With bandwidth around 150 kHz they respond quickly enough for motor drive feedback, battery‑management systems and fast‑acting protection loops. Available in 3.3 V or 5 V supply versions and supporting ranges from 100 A to 200 A, they suit applications that need precise measurement across a wide current span while keeping board space tight. The built‑in over‑current fault output simplifies integration of protective circuitry, and the isolated design reduces interference with surrounding analogue or digital signals. Choosing between voltage options and current ratings lets designers match the sensor to the power domain and control architecture of their project.
