I am working on a custom wireless charging System. I am using the following ICs Transmitter IC: https://www.analog.com/media/en/technical-documentation/data-sheets/LTC6992-1-6992-2-6992-3-6992-4.pdf Receiver IC: https://www.analog.com/media/en/technical-documentation/data-sheets/LTC4126.pdf In circuit designing I took help from Demo Kit DC2663A-KIT: https://www.analog.com/media/en/technical-documentation/user-guides/DC2663A-KIT.pdf
I want LED indicator LEDs that will tell me the different charging states of LEDs( Charging is full, Charging is on, Not charging etc.) The receiver PCB has a LED that can show us these states of charging. But I want to use the Charging states indicator circuit on Transmitter PCB not the receiver PCB. Since both PCBs wont have any physical connection so I am unable to figure out how can I implement this indicator circuit of transmitter PCB.
