Hello,
In our design, we use the DRV8350FS to drive our actuator from a 28V power supply through a three-phase bridge inverter composed of SISS40DN MOS.
We have the following configuration:
- Driver control register: 0x400h
- Gate drive HS register: 0x600h
- Gate drive LS register: 0x300h
- OCP control register: 0x007h
Due to the rather low Qg value of the SISS40DN, we observe fast rise/fall time leading to perturbations on our board.
Is there anything we can do at configuration level of the DRV8350FS that we might have missed ?
Otherwise, what would you suggest to improve that ?
Thank you,
Best regards
Clément
