Original question:

MCT8316ZTEVM: nFAULT enabled when duty cycle is less than 10% in MCT8316ZTEVM

MCT8316ZTEVM: R19 and R26 Values for Slew Rate

Kai He

Part Number: MCT8316ZTEVM

If I want to set Slew rate to 200V/us, according to the datasheet, I need to set R19 to 0 ohm. How about R26?

    Hi Kai, 

    Thanks for your question on the Motor Drives E2E Forum. 

    I will aim to provide an answer on this by the end of the week!

    Best,

    Robert

    Hi Kai,

    It is mentioned in the EVM users guide how to configure slew rate using these resistors but the EVM schematic shows a more visual representation of how to configure the Slew rate with resistors. This makes it a little more clear to see how to adjust slew rate with these resistors. Please see this screenshot below:

    If you want to configure the slew rate to 200V/us, you must DNP R26 and tie SDI/SLEW to AVDD. If this answers your question, please help by marking this thread as resolved.

    Best,

    Robert
