ACT5830 Product Brief, 21-Nov-07 Advanced Information - All Information Subject to Change 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.
