Overview
Description
The RAJ240090/100 evaluation kit consists of an evaluation module (EVM), a USB System Management Bus (SMBus), and an interface adapter. It allows users to evaluate their battery management system using the Renesas RAJ240090 Li-ion Battery Fuel Gauge IC (FGIC) and/or RAJ240100GFP Li-ion Battery Fuel Gauge IC (FGIC).
Additionally, the kit includes the Battery Management System with Fixed Firmware (R-BMS F), which is a fixed-firmware that is easy to use and requires no additional development. It features user-configurable settings for determining the device's different thresholds. The evaluation kit enables a seamless transition from evaluation to customer qualification without the need for firmware development.
Contact your regional agencies/distributors for more details.
