Introduction

The EVALSTGAP2S board allows evaluating all the STGAP2S features while driving a half-bridge power stage with voltage
rating up to 1700 V in TO-220 or TO-247 package.

The board allows to easily select and modify the values of relevant external components in order to facilitate driver’s
performance evaluation under different applicative conditions and fine pre-tuning of the final application’s components.
