Part Number: TPS546D24

Team,

is it possible to lock PMBus access to the device?
Is there some mechanism to prevent write access to device?

My customer wants to prevent unintended modification of the registers since they have multiple devices connected to the bus.

Thanks!

  • Hi Franziskus,

    I believe the (10h) WRITE_PROTECT command will give them the desired functionality.
