Hi.
This is maybe more of a general USB-C question.
We have a USB-C port design with TPS65987D which primarily is meant for connecting laptops.
It can via Power Delivery supply power at 5, 9, 15, 20V all at 3A.
USB Datarole is UFP, providing USB devices for webcam and audio.
Receive video from DP UFP via Displayport alternate mode.
And we are Dual Power role such that you can connect your PC with an USB-A to USB-C cable and still get the USB devices.
(But no DP video then).
However, since we are Dual Power role you can also connect with a USB-C to micro cable.
Can we enable Battery Charging BC 1.2 to effectively become a Dedicated Charging Port ?
Will the TPS65987D keep track of the Power and Data role states and handle the USB2.0 lines accordingly ?
And is it recommended to have BC in such a design ?
Thanks in advance,
Martin Bugge
