3.2.2 Demo #2: Test with a Multimeter and EZ-PD Protocol Analyzer

In this demo, a multimeter is connected to the CY4533 EVK to test the various voltages offered by the USB Type-C power

adapter (or Power Bank). You can also connect an electronic load in parallel with the multimeter to test current capabilities

of the power adapter (or power bank) and the CY4533 EVK.

In addition, you will use the CY4500 EZ-PD

between BCR and the power adapter.
