5.4 Dead Battery Demo
The Dead Battery demo demonstrates the following:
Emulates a scenario of a notebook with a dead battery, which can be charged by connecting a Type-C power adapter to
its Type-C port.
Ability of the CCG2 device to perform the power role of a provider as well as a consumer.
5.4.1 Boards, Cables, and Accessories Needed
The following items are needed to perform this demo:
Items provided with the kit
o
CY4521 EZ-PD CCG2 EVK
Items not provided with the kit:
o
Type-C power adapter (see
o
Digital Multimeter to measure voltage
5.4.2 Running the Dead Battery Demo
1. Use the default jumper settings shown in
PD CCG2 EVK’s base
board and daughter card.
2. In order to create a dead battery scenario, do not connect the 24V DC power adapter provided with the kit to the power
jack J1 of the CCG EVK base board.
3. Because no power is connected to the EVK setup, the CCG2 device on the CCG2 daughter card is not powered, and
thus emulates a dead battery scenario on a notebook. The CCG2 device in the EVK can be powered by connecting a
Type-C power adapter to the Type-C port. As shown in
, connect a Type-C power adapter (not provided with
section) to Type-C port J3 of the CCG EVK base board. LED2 on the CCG2
daughter card and LED1 on the CCG EVK base board glow green to indicate power is ON, and LED2 on the CCG EVK
base board blinks orange to indicate the CCG firmware is executing.

4. When the CCG2 device in the EVK is powered, it establishes a power contract with the Type-C power adapter and starts
consuming power. This can be verified by connecting a digital multimeter to the consumer power output header (J7) of
