Hello @QuirinS,

You can use the "Charge Boot Capacitor" parameter values set by MCSDK workbench for ST EVSPIN32G4-DUAL use case. These default values cover the majority of cases. For specifics use-cases, refer to "AN5789
Considerations on bootstrap circuitry for gate drivers" documentation available here.
