The customer is interesting in using the BQ500212A in a medical patch application. They asked if wireless charging is possible while wearing the patch.

What are the key considerations for this charging application?

Hello

Unfortunately the BQ500212A wireless power TX along with other TX are NRND. Support for the unit are limited. This has been a problem with some customers before.

Charging while wearing the patch is not the best situation and has some risk. This would need to be looked at much closer.

Bill,

I meant BQ51003. We used BQ51003 RX in the design and didn't include the TX device as you indicated it's NRND. What risks are you referring to? Like safety?
