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

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

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.
