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.了解更多
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.了解更多
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.了解更多
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.了解更多
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.了解更多
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.了解更多
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.了解更多
