Application Note
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.
Charge into the future of vehicle electrification with the world's #1 supplier of current sensor ICs for leading EV applications.
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.
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.
This application note can be used to estimate the crosstalk error for adjacent notched busbars in combination with the ACS37610 coreless differential Hall sensor. This information can be useful when designing, for example, the three phases of a traction inverter.
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.
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.
As safety goals multiply throughout the system design process, customers demand smart sensors that can be used to diagnose abnormalities in a system. The built-in Self-Test mode of the A1365 grants users such insight into their systems.
