RTKA489EPRDK0010BU

140W USB Type-C Battery System Reference Design for 2 to 7S Li-Ion

Description

The RTKA489EPRDK0010BU (RTK-G015-EPRSinkCharger (140W)) is a Universal Serial Bus Power Delivery

(USB PD) evaluation board that supports 2 to 7 battery cells in series configuration. The

RTK-G015-EPRSinkCharger is designed with 48V USB-C Port Controller (SPR/EPR TCPC) RAA489400, USB-C

Port Manager (TCPM) R9A02G0151, and On-Board Charger RAA489118. There are two types of RTK-G015-

EPRSinkCharger-140W supports 28V/140W USB Type-C

for the RTK-G015-EPRSinkCharger.

The RTK-G015-EPRSinkCharger supports USB PD 2.0, USB PD 3.1, and USB Type-C Specification. The

RTK-G015-EPRSinkCharger works as a USB Type-C EPR power sink charger or an EPR power bank. The

RTK-G015-EPRSinkCharger 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. The RTK-G015-EPRSinkCharger may 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 1.2.1.0 applies to the RTK-G015-EPRSinkCharger.

Page 11: Charging Current Limits
RTKA489EPRDK0010BU 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.

FW is generated by VIDWriter 1.2.1.0 (see Firmware Writing to the R9A02G0151 on RTK-G015-EPRSinkCharger). If SW1 does not have a suitable charging current value and/or user does not want to set MaxSysVol and MinSysVol as standard values, user needs to set SW1 to SW position 0 and set the expected charging current value, MaxSysVol and MinSysVol.
