heating between TX and RX when no pulling current (bq51013B)

Other Parts Discussed in Thread: BQ51013B

Hello,

I wish to use bq51013b part for wireless powering a bqxxxxx lipo charger.

I know that I can pull high the EN1 and EN2 pin to stop the transfert of the TX part. But it's not easy to implement, the bqxxxxx has an open drain for indicate charge complete but how to wire this to the EN1 and EN2? I asked before but I'm not sure it's a good idea()

So I think the simplest way is to let EN1 EN2 pulled low.

The question is, TX will transfert permanently, but since bqxxxxx charger will stop pulling current when the battery is charged, the heat between TX and RX will be the same than when pulling current or is it very low?

thank you for your help
