Overview

Renesas' lithium-ion battery management (Li-ion) solution is built around a battery management IC that offers a low-power microcontroller (MCU) and high-performance analog front-end (AFE) in a single package, along with an evaluation board, sample code and other tools to support the development of safe, secure and high-performance Li-ion batteries.

Target applications for Li-ion battery management solutions include notebook and laptop computers, power tools, cordless vacuums, and motor-assisted bikes.
