EVM User's Guide: UCC217XXQDWEVM-054
UCC217xx and ISO5x5x Half-Bridge EVM User's Guide for
Wolfspeed 1200-V SiC Platforms
The UCC217XXQDWEVM-054 is a compact, half-bridge gate driver board consisting of two single-channel
isolated gate drivers. It provides isolated bias supply, drive current, protection and monitoring needed for driving
several different models of Wolfspeed silicon-carbide (SiC) MOSFET modules and other IGBT or SiC MOSFET
modules with a similar pinout. The on-board DC-DC transformers can provide adjustable isolated voltage.
The board's compact form factor, combined with UCC217xx's 5.7kVrms reinforced isolation, makes it a good
candidate for doing high voltage tests, such as double-pulse tests and short-circuit tests, with the Wolfspeed
SiC modules. The board can also be used with all variants of the UCC217xx and ISO5x5x family with minimal
on-board modifications.
This user's guide describes the characteristics, operation and use of the UCC217XX-054 Evaluation Module
(EVM). It also includes instructions to adjust different gate driver parameters, such as voltage supply and drive
strength, as well as instructions to modify the EVM to be compatible with different UCC217xx and ISO5x5x
variants. A complete schematic diagram, printed circuit board layouts, and bill of materials are included in this
document.
