Smart isolated gate driver with bias supply reference design

PMP23223

Design files

Overview

This reference design demonstrates the combination of UCC21732 gate driver with a UCC14xxx series bias supply. This design can be used to drive a variety of power switches, including connecting directly to a Wolfspeed Silicon Carbide (SiC) field-effect transistor (FET) module. This reference design can serve as either a high-side or low-side driver, or it can be tested with a capacitive imitation load.

Features
  • +18-V and -4-V, 1.5-W isolated bias supply
  • Drives a variety of power switches
  • 10-A source and sink gate drive strength
  • Adjustable desaturation protection
  • Isolated analog sense
