The Allegro ACS37041/2 is an AEC-Q100 qualified, Hall-effect current sensor designed for cost-optimized applications, serving as a direct replacement for shunt resistors. This integrated, self-contained solution offers galvanic isolation and features a low 1.6 m conductor resistance for minimal power dissipation. It provides a voltage output linearly proportional to the primary current, capable of bidirectional sensing up to 30 A. The sensor is available in 5 V and 3.3 V variants and operates within a wide temperature range of 40C to 125C. Its small, 5-pin SOT23-W package makes it suitable for space-constrained designs in industrial motor drivers, clean energy systems (string and microinverters), and personal mobility devices.
