Searching for WPC-Bx tx topology solution

[dzenbo]

Hi all

I need help with project that require IC to be base of multi coil QI charger solution like wpc-B1, B2 and B3 describe. Like here on page 41

I saw this document so don't refer me to it. But this doc created in 2013. Is something has changed since that time? Did NXP (or ether manufacurer) has any onechip solutions or something with fast implementation time? Anybody meet this problem?

MESSAGE FOR MODERATORS: please relocate this topic into proper category as i haven't found any better than place it in Other NXP Solution. God bless you

Hi,

Now we suggest customer to use WCT1111 in B type (Multi-coil) solution, use one chip to control all the coils.

Please refert to the detali in below link:
