Hi team,
Our customer want to know the recommend design of PG Pullup resistor as it requires external pullup. Could you help recommend the pullup resistor value?
Thanks,

Hi Muwei,
Please use the same R_PG range as in the TPS7B85-Q1 datasheet (which has the same PG circuit).

Hi Nick,
Thank you. By the way do you have a schematic example of TPS7B86 with PG pin that we can share with customer? Is it like the one below?
Hi Muwei,
Yes the schematic you've drawn there is how the PG pin can be pulled up. It can also be pulled up to any other voltage rail up to 18V that is not the output voltage of the device as long as the voltage level satisfies a valid logic level.
Regards,
Nick
