Programmable, Multi-Chemistry Fast Charge Management Reference Design

TIDA-00026

Design files

Overview

This reference design is a programmable, monolithic IC solution for fast-charge management of nickel cadmium (NiCd), nickel metal-hydride (NiMH), or lithium-ion (Li-Ion) batteries in single- or multi-chemistry applications. It chooses the proper battery chemistry (either nickel or lithium) and proceeds with the optimal charging and termination algorithms. This process eliminates undesirable, undercharged, or overcharged conditions, and allows accurate and safe termination of fast charge.

Features
  • # Series Cells: 1 to 25S
  • Max Input Volts: 25V
  • Max Charge Current: 1A
  • Topology: Switch-Mode

A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
