Using EVALSTGAP1AS with STEVAL-PCC009V2 and
STGAP1AS evaluation software
Using the EVALSTGAP1AS board in connection with the 'STGAP1AS evaluation software'
and the STEVAL-PCC009V2 interface board it is possible to evaluate the device
functionalities and driving two EVALSTGAP1AS boards implementing independent, half
bridge, or interleaved configuration of power switches.
The software allows saving the device parameters configuration in a dedicated file that can
be reloaded whenever it is necessary, for example after the board power-on. The 'Save' and
'Load' buttons on the bottom-left side of the STGAP1AS configuration panel (Figure 10)
have these functions.

Single EVALSTGAP1AS board setup example
1. VDD = 3.3 V from the STEVAL-PCC009V2: closing JP4 and JP6
2. VH from external power supply (J2 connector)
3. VL = GNDISO (JP5 closed)
4. PWM input signals can be applied to the J3 connector (IN-, IN+)
