The board is supplied by the 5 V VAUX connection, which fed the isolated DC-DC converters for the low-side and

high-side driving sections. The gate drivers can be directly supplied by VAUX if a 5 V MCU is used, or by the

onboard linear regulator if a 3.3 V MCU is used. The PWM and Reset inputs can be easily controlled through

dedicated connectors while diagnostic outputs are connected to an onboard LED.

Device protection features (Desaturation, Soft turn-off and Miller clamp) are connected to the recommended

network on the board and can be easily evaluated through the board test points.

Dual input pins allow the selection of signal polarity control and implementation of HW interlocking protection to

avoid cross-conduction in case of controller malfunction.

The device allows implementing negative gate driving, and the on-board isolated DC-DC converters allow working

with optimized driving voltage for SiC MOSFETs.

The EVLSTGAP3S6S board allows evaluating all of the STGAP3S6S features while operating with a bus voltage

up to 520 V. It is possible to increase the bus voltage up to 1200 V by replacing the two SiC MOSFETs with

appropriate devices in a H2PAK-7 package and the C4 capacitance if needed.
