Resolved! STWBC86: Does it come pre-loaded with firmware?
Hi all, I'm designing a Qi charger and I'm wondering if I'll need to flash each IC in production, or if they come pre-loaded with firmware? If I have to flash them, is it done via the I²C interface? Thanks!
Resolved! STWBC86 TX powers on and off every 4 seconds
Hi all, I designed a custom 5W charger around the STWBC86. I programmed the config and patch found in STSW-WBC86FWBPP to the IC using WPSTUDIO and I got it to charge my device (another custom circuit, this one using a TI BQ51050 receiver IC)... for 4...
Wireless charger with STWLC98
My question is about the STWLC98 chip. I am looking to integrate this chip into a wireless charger for a university project, so I need the source code of an application to be able to work on the chip and achieve my goal of making a wireless charger t...
