Tool/software:
Hello,
I am curious if anyone knows the maximum power that can be supplied by the power supply when powered passively off of the 13.56-MHz H-Field. I know the RF430FRL152H combined GPIOs are limited to 500uA which at 1.5V would be 0.75mW. I'd like to power an external chip from the RF power supply but not sure if that would allow more than 500 uA to be drawn? Not sure if that's a limit of the GPIOs specifically or the power supply itself off of the RF field. For comparison the NXP Semiconductors NTP53x2 NFC chip says it can provide up to 30mW off the harvested field which is quite a bit more.
Thanks,
Nick
