UCC28951: deadband setting

Tool/software:

Hello,

Posting on behalf of my customer.  Kindly review and provide feedback.

"We have a question regarding UCC28951 deadband setting. The datasheet recommends minimum 13kohm Res(DELAB, DELCD) for fixed deadtime around 250ns. But if we want to set 100ns for fixed deadtime, the required Res is around 5.6kOhm, which is lower than the recommended minimum. We have set 5.6kOhm in the IC and it gives 100ns deadtime in real time.

 Our question is, can this cause any other problem ? Or can this affect CS signal?"

Thanks,

Tom
