Part Number: DRV8220EVM Other Parts Discussed in Thread: DRV8220 , Dear Team:
If the customer increases the operating frequency, the current will become a triangle wave as shown in the figure below
Is this normal? What is the reason?
Thank you for your question.
Please find my schematic review in the attached PDF. Usually damage like this occurs due to some sort of Abs max violation. I suggest looking into the bulk capacitances on VM as suggested in the pdf.
