User Manual for HPD GD BOARD G1 SiC 

Gate Driver Board 

About this document 

Scope and purpose 
This  application  note  describes  the  features  of  and  how  to  operate  the  evaluation  gate  driver  board  
HPD GD BOARD G1 SiC for HybridPACK™ Drive CoolSiC™ modules.  
 

Intended audience 

Experienced engineers designing gate drive boards for HybridPACK™ Drive CoolSiC™ modules. 

 

Evaluation Board 

This board is to be used during the design-in process for evaluating and measuring characteristic curves, and 
for checking datasheet specifications. 

The evaluation gate driver board was designed to support customers during their first steps in designing 
applications with the HybridPACK™ Drive power module and gate driver EiceDRIVER

TM

. An evaluation board is 

not intended to be an optimal design for every specific requirement. But it gives a good starting point and 
useful design hints for serial development. Furthermore, practical experience from the power module switching 
characteristic as well as the gate driver features can be obtained in the lab at a minimum effort by using such 
evaluation tools. 

 

Note:

 

PCB and auxiliary circuits are NOT optimized for  final customer design.
