DRV8353RS-EVM: DRV8353RS EVM Board not working

Electrical Junior

Part Number: DRV8353RS-EVM
Other Parts Discussed in Thread: DRV8301

We are using the DRV8353RS EVM and the board is not working properly. We have trouble with the gate not switching properly. The gate driving output of the board is at too low of a voltage to switch the MOSFETs. We do not know what the problem is. We have encountered the same problem with the DRV8301 as well where we used a custom PCB for development.

    Hello,

    What is the voltage being supplied to the EVM? The EVM is unmodified, and still not working?

    The board will be able to work if the user's guide is followed. Can I see waveforms of operation to help me determine what the issue is?

    Thanks,

    Joseph
