TPS65987D: Can I float extraneous VBUS2 and PP_HV2?

Joshua Kim

Part Number: TPS65987D

Dear,

I'm making a sink only device. I use VBUS1 and PP_HV1. Can I float extraneous VBUS2 and PP_HV2 like the attached circuit?

Thanks again,

Hi Jeong,

It is recommended to short VBUS1 and VBUS2 pins together, even if you are not using one of the power paths.

However, the unused PPHV pins can be grounded.

If this answers your question, PLEASE select This resolved my issue

Thank you,
Eric
