Overview

Description

This is a USB-certified single port power bank reference design. It can connect 2 to 4 cells (default is 3 cells) in series and has a battery monitor function on this board. When combined with a lithium-ion battery, this reference can realize a Power Bank.

The USB Type-C® port is Dual Role Power (DRP), supporting both sink mode to charge the battery and source mode to support programmable power supply (PPS). The standard firmware provided is designed to work with 2 cells and 4 cells other than the 3 cells default by changing the board settings.

USB certification: 
TID: 1090007, RTK-251-1PowerBank3, 100W(Sink)/45W(Source)
TID: 1090008, RTK-251-1PowerBank3, 100W(Sink)/15W PPS(Source)

The following tool is provided for firmware customization:

  • Firmware generation support tool (PDC image generator, PDC-IMGGEN): GUI tool that can change parameters of USB PD protocols.
