Product Summary

The MAX8725ETI is a multichemistry battery charger with automatic system power selector. It uses analog inputs to control charge current and voltage, and can be programmed by a host microcontroller (µC) or hardwired. High efficiency is achieved through use of buck topology with synchronous rectification. Its applications include Notebook and Subnotebook Computers, Hand-Held Data Terminals.
