22 / 24 page High-Precision Linear Hall-Effect-Based Current Sensor IC With 200 µΩ Current Conductor ACS780xLR 22 Allegro MicroSystems, LLC 115 Northeast Cutoff Worcester, Massachusetts 01615-0036 U.S.A. 1.508.853.5000; www.allegromicro.com Figure 4: ACS780 Current Trace Approach – the desired range of the angle θ is from 0° to 85° ENCROACHMENT UNDER THE IC In the LR package, the encroachment of the current-carrying trace under the device actually changes the path of the current flowing through the IP bus. This can cause a change in the cou- pling factor of the IP bus to the IC and can significantly reduce deviceperformance.UsingANSYSMaxwellElectromagnetic Suites, the current density and magnetic field generated from the currentflowweresimulated.InFigure5,thereareresultsfrom two different simulations. The first is the case where the current trace leading up to the IP bus terminates at the desired point. The second case is where the current trace encroaches far up the IP bus. The red arrows in both simulations represent the areas of high current density. In the simulation with no excess overlap, the red areas, and hence the current density, are very different from the simulation with the excess overlap. It was also observed that the field on H1 was larger when there was no excess overlap. This can be observed by the darker shade of blue.
