3-cell Li-ion Battery Power Bank Reference Board with USB-Type-C® Port
Jump to Page Section:
Overview
Description
This is a USB certified reference solution of a 2~4 cells Li-ion battery power bank. This solution consist of PD controller R9A02G011 to work with Buck-Boost charger ISL9238C, for voltage conversion as well as battery charging.
The USB Type-C® port supports Dual Role Power (DRP) and has capability to support Programable Power Supply (PPS) in Source role. It also supports Sink-only role to evaluate the product that has battery inside and requires USB Type-C® port for charging.
For firmware (software) design, this evaluation board comes with:
- Firmware generation tool (PDC image generator, PDC-IMGGEN), a GUI tool enable engineer to tweak the required USB PD function, and with USB PD3.0 compliance firmware, providing fast turnaround solution for standard USB PD features.
- Software Development Kit (SDK), with USB PD3.0 compliance firmware, providing great flexibility for engineer to utilize R9A02G011 PDC’s resource to implement additional or proprietary functions.
By providing such reference solution, enable engineer to start product design right away.
