100W USB Type-C Battery System Reference Design for 2 to 7S Li-Ion

Description

The RTK0EUG011D09020BJ (RTK-251-SinkCharger-RAA489118) is an evaluation board for Universal Serial Bus

Power Delivery (USB PD). The RTK-251-SinkCharger-RAA489118 is designed with USB PD controller

R9A02G011 and On-Board Charger RAA489118 to support 2 to 7 battery cells in series configuration. This

document is the instruction manual for the RTK-251-SinkCharger-RAA489118.

The RTK-251-SinkCharger-RAA489118 supports USB PD 2.0, USB PD 3.1, and USB Type-C

RTK-251-SinkCharger-RAA489118 works as a USB Type-C power sink charger or a power bank. The board does

not have a battery protection circuit on it, so Renesas strongly recommends using a battery module with Renesas'

Battery Management System to avoid over-discharging under the power bank mode. The RTK-251-SinkCharger-

RAA489118 can be combined with an Evaluation Module of the Battery Fuel Gauging IC (FGIC) RAJ2400100 with

Filefish to realize a complete Battery Management System (BMS).

The configuration switches enable the selection of the number of battery cells, the maximum charge current and

the operating mode.

VIDWriter 1.1.0.0 applies to the RTK-251-SinkCharger-RAA489118.

Page 9: Charging Current Limits
RTK0EUG011D09020BJ Manual MaxSysVol represents the maximum battery charging voltage. It is defined as Full in this document. If VBAT reaches the Full value, the charger operates in Constant Voltage mode. MinSysVol represents the minimum allowed voltage during discharging mode. It is defined as Empty in this document. In charging mode, when VBAT is less than the Empty value, the Charger trickle charges the battery at a low current level.

IMPORTANT: The RTK-251-SinkCharger-RAA489118 does not have a battery protection circuit on the board, so, Renesas strongly recommends using a battery module with Renesas’ Battery Management System to avoid over discharging under the power bank mode. RTK-251-SinkCharger-RAA489118 can support power bank mode as long as the battery module uses a protection circuit to avoid over-discharge and over-temperature.
