The CY4541 CCG4 daughter card consists of both a power provider and a power consumer circuitry for each Type-C port. The
CCG4 device controls this circuitry and decides the source of the power for both CCG EVK base boards and the CY4541 CCG4
daughter card. The power input header on each CCG EVK base board can receive DC power directly. The power output header
on the CCG EVK base board can receive and source power directly when a USB Type-C power adapter is connected to Type-C
port 1 or 2. The CY4541 CCG4 daughter card receives power either from CCG EVK base board 1 or from CCG EVK base board
2 (whichever is higher).
In a CY4541 EZ-PD CCG4 EVK enabled dual Type-C PC design, the entire EVK can be powered using the following methods:
Scenario 1
: A DC power adapter is connected to the DC power jack (J1) on CCG EVK base board 1 or CCG EVK base board 2
In this scenario, the CCG4 device turns on the power provider control circuitry and power is available on the power input headers.
Wires must be connected between the power input headers (J12) on both the CCG EVK base boards (shown by the dotted line
