Current Sensor ICs
DC to 5MHz, High-Accuracy Current Sensor with Reference or Fault Output
ACS37029-32
Markets Served
The ACS37029, ACS37030, ACS37031, and ACS37032 current sensors provide precise current measurements across a wide frequency range (DC to 5MHz) using both Hall-effect and inductive sensing. ACS37030 and ACS37031 offer a reference voltage output, while ACS37029 and ACS37032 provide a fault output for overcurrent detection. ACS37030 and ACS37032 offer ±20A (LZ only), ±25A (MY only), ±40, and ±65A current measurement ranges. ACS37029 and ACS37031 are the lower sensitivity variants, offering ±90A and ±150A current measurement ranges.

Part Number Specifications and Availability
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.
