GENERAL DESCRIPTION
The patent-pending ACT5830 is a complete, inte-
grated power management solution that is ideal for
mid-high and mobile phones. This device integrates
a linear Li+ battery charger with an internal power
MOSFET, a high efficiency 350mA DC/DC con-
verter, eight low dropout linear regulators, a reset
output, and two N-Channel open drain switches,
and an I
2
C Serial Interface to achieve flexibility for
programming LDO outputs and individual on/off
control.
The charger is a complete, thermally-regulated,
stand-alone single-cell linear Li+ battery charger
that incorporates an internal power MOSFET for
constant-current/constant-voltage control. The
charger includes a variety of value-added features,
and it is programmable via the I
2
C-Interface to con-
trol charging current, termination voltage, along with
safety features and operation modes.
The ACT5830 is available in a compact 5mm x
5mm 40-pin Thin-QFN package that is just 0.75mm
thin.
