Figure 16. Power-Wake Implementation

7.3.3.11 Port Power Management (PPM)

PPM is the intelligent and dynamic allocation of power made possible with the use of the LD_DET pin. PPM is for

systems that have multiple charging ports but cannot power them all at their maximum charging current

simultaneously.

Goals of PPM are:

•

Enhanced user experience, because the user needs not to search for a high-current charging port.

•

Lowered cost and size of the power supply needed for implementing high-current charging in a multiport

system.
