I am developing a solution using a STWBC2-HP tx running from a 24VDC supply to drive a STWLC99 rx and need to use the STSC protocol to achieve 50~100W. This is for bespoke power transfer rather than a conventional charger. I am basing the design on the steval-wbc2tx50 datasheet with ratings upgraded for the extra power. Also referring to '100w-wireless-charging-solution-based-on-stwbc2-hp-and-stwlc99-rayna-wang.pdf' from ST's website.
Does the STSC protocol require Qi1.3 (ie does it need STSAFE-A110) and how do I enable this?
Do I just need to configure the current and voltage parameters via the UART for this power level?
Thanks.
