Part Number: BQ500414Q

Hello, I am a graduate student interested in the wireless power transfer technology.

I was wondering if I can get some information about PWR633 EMI shield that can reduce EMI with BQ500414Q.

I am studied about multiple TX coil system and how to operate a TX depending on RX position.

I found some information about BQ500414Q, but I couldn't find about PWR633 part that is a pattern to reduce EMI.

Could you let me know if there is a product for the pattern mentioned in the PWR633 patent(US 9230732 B2)?

I am looking forward to your reply

Sincerely,

Sungryul Huh

Hello Sungryul Huh

We have several customer that used the BQ500414Q / PWR633 EMI shield. But this design is a 5W solution and customers have switched to 15W solutions, the BQ500414Q is NRND now.. Designs that are still available are not clear.

What type of info are you looking for on this system?
