Allegro High Voltage Gate Drivers
GaN and SiC power devices are expected to rapidly gain market share in electric vehicle and green energy applications. Allegro’s isolated gate driver solutions use a single, small-footprint package that integrates an isolated gate driver, an isolated power supply, and associated passive components.
This significantly reduces system design time and complexity and makes it possible for designers to take advantage of the full efficiency benefits that WBG switches provide. Additionally, the reduced system design time and complexity help alleviate the need for additional engineering and design resource
