Overview
Description
This is a single-port reference design for implementing battery systems with 2 to 4 cells connected in series. This reference design supports a mode where power is only supplied from the USB Type-C® port and a mode that enables a power bank in combination with a lithium-ion battery with a battery management system (BMS).
Because there is some loss in the cable, onboard charger, and board, the USB PD controller requires appropriate USB-C input levels to the USB Type-C source device to properly operate the battery system. Switches on this evaluation board allow you to select the number of batteries in series and the charging current.
The firmware (software) for this evaluation board is generated by an instruction tool called VIDWriter. More detailed settings that VIDWriter does not support can be made with the ImageGen Tool. ImageGen can be downloaded from the R9A02G011 product page.
