Kit Operation
This chapter describes how to configure the CY4541 EZ-PD CCG4 EVK to demonstrate the operation and functionality of the
CCG4 as a DRP device. It demonstrates that each Type-C port of a DRP device can act as a power provider or a power consumer.
It also provides details about connecting a USB host (PC) to either a device (USB pen drive/display monitor) or a USB Type-C
power adapter through the CY4541 EZ-PD CCG4 EVK board.
This chapter provides details of the following demos:
a. DRP and SuperSpeed USB demo
– This demo shows the ability of CCG4 to control two Type-C ports simultaneously. In
this demo, both Type-C ports act as power providers.
b. Dead Battery Charging demo
– This demo shows the ability of CCG4 to consume power from a USB Type-C power adapter
when the external DC power supply is absent. This demonstrates a dead battery notebook, which can be powered by
connecting the USB Type-C power adapter to its Type-C port.
c.
DisplayPort Alternate Mode demo -- This demo shows the ability of CCG4 to transfer DisplayPort signals to a display monitor
over the Type-C interface.
Before starting with the demos, let us understand power supply system of the CY4541 EZ-PD CCG4 EVK in detail.
6.1 Power Supply Connections
A PC with two USB 3.0 ports and a DisplayPort, along with the CY4541 EZ-PD CCG4 EVK, is equivalent to a PD-enabled dual
Type-C port PC as shown in
. In a real Type-C notebook design, power from the power output header (J7) of the CCG
EVK base board acting as the USB Type-C power adapter is connected to a Battery Charger Circuit (BCC) of a USB 3.0
notebook/PC. On the CCG4 EVK, the DC power jack (J1) on the CCG EVK base board is provided for demonstration purposes
only since the internal supply from the Power Management IC (PMIC) is not available. A notebook power adapter (as shown in
would be connected to the “ORing” controller block which supplies power to the Battery Charger Circuit (BCC).
In a real system, the power input header (J12) of CCG EVK base board 2 would be connected to the output of the PMIC. Since
this tapping of power from the PMIC is not available in existing PCs, wires are directly connected between the power output and
power input headers of CCG EVK base boards to mimic the Type-C notebook design using CY4541 EZ-PD CCG4 EVK.
Power being provided to the CCG4 EVK would come from a PMIC in the Notebook, and the input source to that PMIC could either
be the notebook battery, a notebook power adapter or a USB Type-C power adapter. Hence, in a Notebook it is possible to connect
both the DC power adapter and the USB Type-C power adapter. However, in the case of the CY4541 EZ-
PD™ CCG4 EVK, since
the internal power points to the Notebook are inaccessible, it is mandatory that power is not provided via the power jack J1 of
either of the CCG EVK base boards when the CY4541 EZ-
PD™ CCG4 EVK is powered by a USB Type-C power adapter (as
shown in
) as this can damage the EVK boards. This restriction is not due to a limitation on the CCG4
device, but only because of the inaccessibility of the internal power points inside a Notebook/PC.
