We are hoping to develop a wireless charger around your chips. Our system needs to be WPC 1.1 compliant.
A) Power Transmitter Solution:
Our preference is 5V input operation (for USB compatibility). While our first product is a single coil guided positioning system, and the 500211A suits us well in that regard, we prefer 500410A to streamline further development when we build free positioning systems. Please clarify the following:
1. Is 5V input possible with 410A? Your EVM does provide for it with a boost regulator module, but are there any issues in this approach (apart from impacting the BOM and form factor)?
2. Is there a ready (tested) solution for a single coil transmitter system based on the 410A, with 5V input?
B) Communications:
As I understand, the chips come with TI firmware which we cannot (or should not) change. How can we achieve sending (receiving) proprietary packets to (from) the receiver module? Do your EVMs for 211A and 410A provide this functionality?
Thanks,
Tapan.
