Hi.
I'm developing a PCB circuit with a microcontroller and the NFC PN7150.
My hardware doesn't need a battery to work, so my question is:
Do the battery related pins VBAT1, VBAT2 and VBAT need to be connected to a 5V source or can they be left unused?
I can't find any information on that subject, so it is assumed that there will always be a backup battery.
Any comment or suggestion is welcome

Need to be connected to a 5V source.
Please kindly refer to the 12.5.3.2 Configuration 2: supply connection in case a 5 V supply is used to generate RF field with the use of TXLDO of the datasheet as the link.
