I'm using SE051
I want to use the secure element feature to meet the Matter security criteria and the 14443A feature to implement Tap to Pair.
VIN Pin : in 3.3V DC Global net
Vout Pin pad to VCC Pin pad Connection.
SE051 switches on/off between VIN and Vout via the ENA pin.
When the switch is turned off, 14443a is activated..
Can the magnetically induced power from the NFC reader to the 14443 antenna affect the VIN?
Is the internal power switch of the SE051 protected against reverse current?
If this is not taken into consideration, can you suggest a solution?
Can I implement Matter's Tap to pair using SE051's 14443 feature?

Hi @Devkun ,
Can the magnetically induced power from the NFC reader to the 14443 antenna affect the VIN?
-No, it just supplies power to the same domain powered by VCC pin.
Have a great day,
