LM5064EVK: About operation of Pi-commander

Part Number: LM5064EVK

Hi,

I evaluate LM5064EVK with Pi-commander.
I want to disable MOSFET gate shutdown by setting "1" to 0xD7 with the PMbus command.
I thought you would set it with PMbus Coefficient editor, but 0xD7 address is not displayed.
How can I disable it?

Also, are there any application notes on how to use Pi-commander?

Best Regards,
Yuto Sakai

    Yuto,

    PMBus coefficients are for reading volts, amps, current, watts, temp, not for setting digital fault response.   For fault masking, use the fault configuration portion of the GUI.  Check the Fault Masking box and select the fault you wish to mask to ethier gate, alert or both gate and alert.  Note if you disable the circuit breaker gate shutdown, you will most certainly destroy your FET in an output short circuit condition so do this only in your Engineering evaluation recognizing you may loose a few FETs along the way.
