Take a look at the test report for TIDA-00623, it has some wave forms that can be used as a reference.
I suspect this is the ping used to detect an RX that is sent every 400ms to 500ms. The TX will detect a change in the ping pulse and transition to…
Hi Yuki
TIDA-00334 is an older design that I did with the bq500212A. A better newer better design is TIDA-00623, based on the bq50002A & bq500511A. The performance is better and thermals will be better. Circuit layout area is about the same. …
Other Parts Discussed in Thread: TIDA-00762 , TIDA-00623 , BQ50002 , BQ500511 Hello,
I come again for your help.
After some research, I decided to use tida-00623(5W) or tida-00762(1W).
tida-00762 use a 6.5 uH coil and I found that this coil should fit :

Does TI have a wireless charger TX solution with low cost for low power device (ex. 5V/ 250mA)?
Take a look at the TIDA-00415, this is a low power application of the bq500212A
Does TI have a small circuit solution (ex. without MOS driver、current…
