The proliferation of high-voltage and AC-connected electronics in systems such as electric vehicles and industrial automation is increasing the need to control, monitor, and protect the equipment we interact with daily. Isolated current sensing fulfills a key need in these areas by providing critical operational measurements. There are multiple implementations and solutions for isolated current sensing, with significant trade-offs between isolation levels, performance, printed circuit board (PCB) space, and cost.

This white paper explains how to meet the growing need for isolated current sensing while overcoming the technical and cost barriers typically associated with it. You will learn how zero-drift Hall-effect current sensors offer many advantages over implementations such as isolated shunt-based, closed-loop magnetic and isolated in-package Hall-effect sensors – including higher energy efficiency and operating voltages, and increased performance.
