STWLC38 FOD tuning BPP and EPP configuration

pEEter · ‎2024-09-03

Hello, I have some questions regarding a problem with a BPP receiver I am designing. After performing tuning, the FOD configuration on the STWLC38 works well with BPP chargers, but some EPP chargers will trip FOD when the receiver is placed.

Is it possible to use two different FOD configurations on the STWLC38 for BPP and EPP even if the STWLC38 is configured as a BPP receiver?

Is it possible to change the STWLC38 FOD parameters by sending I2C messages without needing to reprogram the RX?

If the above two are not possible, is it possible to implement this with custom firmware?

Thank you!
