Description

The UCC21551CQEVM-079 is a two copper layer PCB containing multiple test points and jumpers to fully evaluate the functionality of the UCC21551 gate driver. The EVM features PWM input control, onboard adjustable power supply, sockets for discrete FETs, external active clamp for low side protection, bootstrapped high side power supply, negative gate voltage capability, configurable deadtime switches, EN/DIS jumpers, and socket for Wolfspeed XM3 SiC-based half bridge power modules. The layout has been optimized to minimize gate loop area for each channel and placement of bypass capacitors allow for clean and sharp signal reading with minimal noise interference.
