GENERAL DESCRIPTION

The patent-pending ACT5830 is a complete,

integrated 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 converter, eight low dropout linear

regulators, a reset output, and two N-Channel open

drain switches, and an I2C 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 I2C-Interface to

control 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.
