評估板CY4532 EZ-PD CCG3PA EVK

The CY4532 EZ-PD™ CCG3PA Evaluation Kit (EVK) is based on the CCG3PA product family of Cypress’s USB Type-C microcontrollers. This EVK is intended to be an evaluation vehicle for USB Type-C Power Adapter (PA) and USB Type-C Power Bank (PB) applications. The kit can be configured for a PA or PB application using a combination of firmware, jumper settings on the kit hardware, and external accessories. The following paragraphs provide a brief description of both applications:

USB Type-C Power Adapter (PA): To charge a device such as a mobile phone or notebook which supports battery charging through the Type-C interface. The device can be connected to the Type-C port on the CY4532 EVK’s Main Board to be charged as per the USB Power Delivery (PD) protocol. This application requires a DC input to be supplied to the EVK.

In addition to charging through the USB Type-C port, the EVK also supports charging through a USB Type-A port to enable battery charging of legacy devices. The CY4532 EVK supports Battery Charging (BC) 1.2, Qualcomm Quick Charge (QC) 3.0, Apple 2.4A charging and Samsung Adaptive Fast Charging (AFC) charging protocols on the USB Type-A port.

USB Type-C Power Bank (PB): This application is similar to the PA application. Here, a 1-Cell or 2-Cell Lithium-ion battery, which is connected to the CY4532 EVK acts as the power source to support charging on USB Type-C and USB Type-A ports. In addition, the battery can be charged using a USB Type-C Power Adapter connected to the USB Type-C port of the EVK’s Main Board.

In addition to the applications described above, the CY4532 Power Board can be used as a Programmer for Cypress EZ-PD CCGx Products supporting Configuration Channel (CC) bootloading. Refer to 5. for more details.
