Complete System Power Protection Design Guide

Abstract

A power delivery system is subject to many electric hazards. Along the electrical path, inrush currents due to storage capacitors, reverse currents due to wiring errors or power outages, overvoltages and undervoltages can induce degradation or irreversible damage. We'll first review the shortcomings of typical non-integrated protection solutions, including those with high BOMs, large PCB real estate, high tolerance, and time-consuming qualification. Subsequently, we'll introduce a highly integrated family of protection ICs with protection features up to 6A and up to ±60V.
