EZ-PD™ Protocol Analyzer CY4500-EPR

Kit Contents

• CY4500-Extended power range (EPR)
• USB 2.0 Type-A to Micro-B cable
• Six jumper wires (five inches each)
• Quick start guide (this document)

Before You Start

Ensure that you have the following:

• A PC with at least one Type-A port
• A USB-PD source device
• A USB-PD sink device

Step 1: Connect the CY4500-EPR Kit

Connect the CY4500-EPR kit to the PC using the USB 2.0 Type-A to Micro-B cable. Observe that the LED1 blinks white continuously.

Step 3: Launch EZ-PD™ Protocol Analyzer Utility

1. Download and install the EZ-PD™ Protocol Analyzer Utility from the Infineon website.
2. Start the EZ-PD™ Protocol Analyzer Utility.
3. On the utility, click the start icon.
4. Select Action > Start to capture the data.
5. Once the capture starts, the LED1 on the CY4500-EPR turns green.

Step 4: Connect USB-PD Source and Sink

Connect the host and sink device to CY4500-EPR:

• Connect the Type-C plug/receptacle of the CY4500-EPR EZ-PD™ Protocol Analyzer to the host/sink device.
• Connect the other end of the Type-C plug/receptacle of the CY4500-EPR EZ-PD™ Protocol Analyzer to a power adapter or any other device (not provided with the analyzer). For more information, go to CY4500-EPR EZ-PD™ Protocol Analyzer.

Notes

• The older CY4500 EZ-PD™ Protocol Analyzer is compatible with the newer application (even if the application prompts to download new firmware on the device, VBUS will be limited to SPR).
• Ensure that the Type-C host and the power adapter/device is connected to the CY4500-EPR board and does not exceed 5 V on CC lines.
