Case 2:
illustrates an invalid power supply connection as described below:
▪
A DC power adapter is connected to the DC power jack (J1) of CCG EVK base board 2
▪
Wires are connected between the power output header (J7) of CCG EVK base board 1 and the power input header (J12)
of CCG EVK base board 2

6.1.3 Non Recommended Power Supply Connections with Custom Firmware
This section shows the three non-recommended power supply connections, if CY4541 EZ-PD CCG4 EVK is programmed with
custom firmware, which enables both power provider and power consumer path circuitry simultaneously. Default firmware in
CY4541 EZ-PD CCG4 EVK does not enable both provider and consumer paths at the same time, which allows the following power
supply connections with pre-programmed CY4541 EZ-PD CCG4 EVK.
Note
: While modifying the firmware of CCG4 device, care should be taken to not enable the power provider and power consumer
path of CCG4 at the same time.
Case 1:
illustrates non-recommended power supply connection as described below:
▪
A USB Type-C power adapter is connected to Type-C port 1 or Type-C port 2 when a DC power adapter is connected to
DC power jack (J1) of the CCG EVK base board 1
▪
Wires are connected between power input headers (J12) of CCG EVK base board 1 and CCG EVK base board 2
