TPS563219A: PG Pull-Up voltage before VIN is provided

Kazuhiko Hirano

Part Number: TPS563219A

Hello,

At my customer design, the pull-up voltage to a pull-up resistor connected to the PG pin is provided before VIN is provided.
Is this OK as long as the pull-up voltage is below PG absolute maximum input voltage rating 6.5V specified in the datasheet?

Hi Hirano,

The max recommended voltage on PG pin is 5.5V.

And pls note that the PG function will be active after SS time.

Young,

Thank you for your response.
So, is that OK as long as the pull-up voltage is below PG recommended maximum input voltage 5.5V specified in the datasheet?
