Twelve Channel Integrated Power Management
IC for Mobile Handsets
FEATURES
GENERAL DESCRIPTION
• Multiple Patents Pending
• 350mA, PWM Step-Down DC/DC Converter
• Eight I2C-Programmable, Low Noise LDOs
− Three Optimized for RF Section Power
− Five Optimized for BB Section Power
• Li+ Battery Charger with Integrated MOSFET
− Charger Current Monitor Output (VICHG)
− Charger ON/OFF Control Pin
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.
• Two N-channel Open Drain Switches
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.
• Minimal External Components
• I2CTM Serial Interface
− Configurable Operating Modes
• AC-OK and RESET Outputs
• 5×5mm, Thin-QFN (TQFN55-40) Package
− Only 0.75mm Height
− RoHS-Compliant
The ACT5830 is available in a compact 5mm x
5mm 40-pin Thin-QFN package that is just 0.75mm
thin.
APPLICATIONS
• GSM or CDMA Mobile Phones
