FUJITSU SEMICONDUCTOR DATA SHEET DS04-27713-1E ASSP For Power Supply Applications (Secondary Battery) Sensor IC For Li-Ion Battery Pack Control MB39F101 ■ DESCRIPTION The MB39F101 is a Li-ion battery pack control IC for 3/4-cell series Li-ion battery packs in notebook PCs. The MB39F101 is composed of 10-bit A/D converter where battery information received from protection IC is processed digitally, 1280-bit flash memory which stores battery initial information and control information, and I2C controlling circuit which communicates with main body of PC. Deleting the microprocessor in the battery pack becomes possible by setting using MB3838A (protection IC made by Fujitsu) .
