Product Summary

The max1772eei is a highly-integrated, multichemistry battery-charger control IC that simplifies the construction of accurate and efficient chargers. The max1772eei uses analog inputs to control charge current and voltage and can be programmed by the host or hardwired. High efficiency of the max1772eei is achieved by a buck topology with synchronous rectification. Applications include (1)Notebook and Subnotebook Computers; (2)Personal Digital Assistants; (3)Hand-Held Terminals.
