DC to 5MHz, High-Accuracy Current Sensor with Reference or Fault Output

ACS37030, ACS37032

The ACS37030/2 current sensors provide precise current measurements across a wide frequency range (DC to 5MHz) using both Hall-effect and inductive sensing. The ACS37030 offers a reference voltage output, while the ACS37032 provides a fault output for overcurrent detection.

The ACS37030 and the ACS37032 are offered in two fused-lead SOIC-6 package options. The LZ package has a lower conductor resistance versus standard SOIC-8 packages and supports higher isolation of up to 840VRMS basic isolation or 420VRMS reinforced isolation. The MY package is a widebody SOIC-6 package that supports a similar reinforced isolation rating to comparable SOICW-16 packages in just half the size

ACS37030/2 Product Overview

The ACS37030 and ACS37032 are fully integrated current sensor IC that senses current flowing through the primary conductor. There are two signal paths utilized, a Hall-effect element path to capture DC and low frequency current information, and an inductive coil path to capture high frequency current information.
