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.
