Description

The L6924D is a fully monolithic linear battery charger, ideal for coke and graphite anode single cell Li-Ion packs that allows a charge management system in a very compact application.

L6924D is the ideal way for space limited applications, like PDA's, hand held, cellular phones and digital cameras. L6924D is realized in BCD6 technology and, in a small VFQFPN 3x3 16 pins package, that integrates all the power elements (the Power pass MOSFET, the reverse blocking diode and the sense resistor).

The maximum application flexibility of the L6924D, is given by the possibility of programming all the features (like pre-charging current, charging current, the pre-charging voltage threshold, the end of charge current threshold and the charging time). When a real basic external wall adapter is used, the L6924D works in Linear Mode and charges the battery in a CC/CV (Constant current/ Constant voltage) profile.
