Application Note
AN296188 - This application note offers guidelines for achieving optimum busbar and notch designs using the Allegro ACS37612 coreless current sensor
AN296155 - This application note will demonstrate techniques on how to avoid coupling the field from high-current transients onto the signal and power lines of current sensors in order to avoid a perceived distortion of the output.
AN296245 - Core material selection, geometry, and air gap dimensions will all impact the performance of the flux concentrator. This note will explain each of these factors and provide a detailed guide for design of a magnetic flux concentrator.
Allegro’s current sensor ICs are ideal for use with solar applications, which include electronic subsystems like solar combiner boxes, DC/DC converters for maximum power point tracking (MPPT), and DC-AC inverters.
Charge into the future of vehicle electrification with the world's #1 supplier of current sensor ICs for leading EV applications.
AN269241 - This application note explains how the Overcurrent-Fault (OCF) feature of Allegro ACS37610 device can be used in application to reliably detect overcurrent conditions and how it can be configured to optimize accuracy and cover different application needs.

Technical Article
This article will discuss two new innovative approaches to measure currents up to 600 A in PCB: a near-lossless Hall-based current sensor with an integrated conductor and a non-invasive standalone core-free and shield-free differential Hall current sensor.
This application note describes multiple methods for measuring and characterizing system bandwidth, with a focus on the impulse response method. Allegro’s ACS720 is the perfect device to validate the test methods outlined here.
Allegro’s Coreless Current Sensing Technology provides a highly accurate method of measuring hundreds or thousands of amps flowing through a busbar or a PCB without needing a concentrator core or U-Shaped Magnetic Shield.
AN296258 - This application note explains how the conductor design can impact the response time of the current measurement for coreless current sensing applications and provides examples of response time to transient current for two types of conductors.
AN296190 - The data contained within this application note allows the user to effectively choose an Allegro current sensor package based on their system’s specifications.
AN296205 - The aim of this document is to provide guidelines for designing a PCB for the ACS37600 while minimizing possible undershoots/overshoots due to a fast current step response.
AN296206 - The goal of this application note is to illustrate and discuss the linearity error of the ACS70310 when sensing fields greater than 2000 G.
