TPS7B86-Q1: PG pin in PTPS7B8601BQDDARQ1

Ernest Yong

Part Number: TPS7B86-Q1

Hello Team,

I have a customer who is looking to use PTPS7B8601BQDDARQ1 as an alternative for PTPS7B8601QDDARQ1.

The difference in this device is the power-good function. As stated in our datasheet, I understand that we can leave the delay pin floating but can I leave the PG pin floating if I do not want to use it?

Thanks.

Hi Ernest,

For TPS7B86-Q1 the PG pin is an open-drain output, so it can be left floating with no issue.

PTPS7B8601BQDDARQ1 and PTPS7B8601QDDARQ1 are pre-production devices. Did you mean to put TPS7B8601BQDDARQ1 and TPS7B8601QDDARQ1?

Regards,

Nick

Hi Nick,

Well noted.

If it is TPS7B8601BQDDARQ1 and TPS7B8601QDDARQ1, what is the proper termination of PG pin in TPS7B8601BQDDARQ1?

Thanks,
