www.DataSheet4U.com FUJITSU SEMICONDUCTOR DATA SHEET DS04-27247-1E ASSP for Power Supply Applications (Secondary battery) DC/DC Converter IC of Synchronous Rectification for charging Li-ion battery MB39A119 ■ DESCRIPTION The MB39A119 is the Nch MOS drive of the synchronous rectification type DC/DC converter IC using pulse-width modulation (PWM) type that can charge Li-ion battery from 1 cell to 4 cells and suitable for down-conversion. This IC integrates built-in comparator for the voltage detection of the AC adapter and switches the power supply to the AC adapter or battery automatically, enabling supply it to system. In addition, the constant voltage control state detection function is built in, which prevents mis-detecting the full charge.
