Applications

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.

It is the ideal way for space limited applications,

like PDA's, hand held, cellular phones and digital

cameras. It 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.
