QSG151: USB Type-C Rechargeable
Not Recommended for New Designs
Battery Pack Reference Design
(SLRDK1000)
SLRDK1000A is a reference design for a small and cost effective
USB Type-C rechargeable battery pack. A Silicon Labs EFM8BB3
Busy Bee microcontroller is used for USB Type-C Power Delivery
(PD) negotiation.
The USB Type-C Battery Pack Reference Design ships with a ready to use demo firmware that is capable of operating in both sink and source mode, delivering up to 15 W
(3.0 A at 5 V) of output power or charging a connected Lithium battery with up to 1.8 A
charge current.
An on-board SEGGER J-Link debugger enables easy customization and development.
