What are the functions of each power supply? That is, in the first picture does Power Supply 1 charge the battery? What is the function of Power Supply 2? Also, What is the function of Load Number 1 and 2 and what is the difference between the two pictures? That is, what is happening in each of the circuits in picture 1 and 2.
Thank You Very Much
Hi,
Power Supply #1 acts as the adapter, so it provides the power needed to charge the battery and power the system load.
Power Supply #2 provides the 3.3 V pull-up rail for SMBus communication.
Load #1 is the system load, and Load #2 is the battery.
The simplified schematic in the BQ24765 datasheet may provide some helpful context:

Both of the pictures in your post show Figure 4 from the User's Guide. Did you mean to send two different pictures?
Best regards,
