ACS37100 Precision Current Sensor IC

The Allegro MicroSystems ACS37100 is a high-performance, fully integrated current sensor IC designed for demanding power monitoring applications. Leveraging advanced Hall effect technology, it delivers precise measurements of AC and DC currents while maintaining reinforced isolation between the primary conductor and the signal path. This makes it ideal for high-voltage systems where safety and accuracy are paramount. The ACS37100 is factory-calibrated, eliminating the need for external programming and simplifying integration into complex designs.

With its ultra-low resistance primary conductor and high bandwidth analog output, the ACS37100 ensures minimal power loss and rapid response times. It supports both fault detection and reference output configurations, enabling flexible system protection and control. Housed in a compact surface-mount package, it is optimized for space-constrained environments and meets rigorous automotive and industrial standards for reliability and performance.
