Hi.

Let me discuss about how to pull up the FLT pin.
Customer is trying to pull up the FLT pin to external power source (3.3V).

Is this all right?

Please contact us if you have any concerns.

  
Best Regards,

    Hi Yusuke,

    There is no concern in using external power source output for FLT pin pull up.
    For some of the application examples in the datasheet, the FLT pin is pulled up to Vout. The Vout is assumed to be always available due to power muxing configuration
