Hi team,

Is it possible to know what the hardware configuration of PP_CABLE should be if customer is not using PP_CABLE pin? floating? connecting to ground?

HI Leroy,

I can check to see if this is detectable and get back to you on Monday.

Can I ask why PP_CABLE is no connect?

Scott

Hi Scott,

It is because the application is using captive cable. looking forward to hearing your comment. Thanks!

Hi Leroy,

It is okay to No Connect PP_Cable if not used. Be sure that PP_CABLE Switch config is marked Not Used.

Scott, Can it be floating if not used?

Hi Leroy,

Yes, it is okay to leave floating. A reference for this is the TPS65987D Power DUO Sink 200 W USB-C PD Reference Design
