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.
