Infineon PMIC I2C connection for first programming
The USB005 I have in front of me includes pull-up to about 3.4 Vdc. I think technically you could program these without pull-up on SCL and SDA (as the dongle will provide it), but your final board needs pull-up if you intend to communicate with the PMICs during operation (from a MCU, etc).
If I understand your application your making a special board just for getting them programmed and then moving them over your final board. I think this is a good idea. Pullup to 3.3 Vdc on the final board can become a bit of a chicken and egg problem if you are relying on the a PMIC output to pull up to 3.3 Vdc. Not just because it wont be there until the PMIC is programmed, but also because several of the PMIC outputs are pulled to ground until they are programmed, causing problems because the I2C lines may be pulled to ground until the PMIC gets programmed.
