Control for Lithium Ion Battery Charging (one cell)

Monolithic IC MM1333

Outline

This IC was developed for use in charging lithium ion batteries. PNP power transistor or P-MOS FET is

mounted externally to control charging. This IC is for use with a single cell only, and provides precise control

of the charging voltage ; the charging current can be set through an external resistance. In addition to the

functions of the MM1332, it incorporates a comparator for full-charge detection.
