TPS53631: How to deal with un-used pins

Part Number: TPS53631

Hello,

If pins of VRHOT, VRRDY, VRFAULT do not be used, how to deal with them? Can they be floated?

If these pins do not be used, can user get similar information or indication via I2C? And then take relative actions via I2C command?

Thank you!

    Thanks for the questions. Please see my comments below.

    These three pins are open drain. If no used, you can leave open.

    If these pins do not be used, can user get similar information or indication via I2C? And then take relative actions via I2C command?

    Please check "Table 5. Supported Protections and Fault Reports" in the TPS53631 full datasheet.

     

    Thanks
