Application Note
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.
Brochure
Allegro MicroSystems has been driving innovation in the current sensor industry for more than 17 years, with a history of first-to-market products that give our customers a competitive edge. Our advanced ICs help you achieve higher efficiency and power density in your designs.
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.
Charge into the future of vehicle electrification with the world's #1 supplier of current sensor ICs for leading EV applications.
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.
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.
