240W USB Type-C Battery System

Overview

Description

The growing demand for portable electronics, power tools, and energy storage solutions is driving the need for flexible, efficient battery systems with longer run times, faster charging, and USB Type-C® connectivity. Consumers expect devices to charge reliably from modern power sources, double as power banks, and maintain safety and performance.

This flexible battery management design supports systems with 2 to 7 lithium-ion cells connected in series. It enables direct charging from USB Type-C ports and power bank functionality, ensuring versatility for a wide range of applications. Intelligent power management compensates for cable and circuitry losses, delivering efficient and safe charging. Adjustable configuration options allow designers to tailor battery pack voltage and charging current, offering a scalable, versatile approach for both portable and industrial applications.

System Benefits:

  • Supports 2 to 7 battery cells and dynamic power roles (sink or source), enabling versatile designs for both charging devices and delivering power as a power bank.
  • Delivers up to 240W with smart power management, ensuring safe and reliable charging.
  • Software-configurable settings reduce hardware complexity, speeding up development.
