Nine Channel PMU for Mobile Phones
FEATURES
GENERAL DESCRIPTION
• Multiple Patents Pending
• Li+ Battery Charger with Integrated MOSFET
− ON/OFF Control
The patent-pending ACT5810 is a complete, integrated power management solution that is ideal for
CDMA and GSM mobile phones. This device integrates a linear Li+ battery charger with an internal
power MOSFET, six low dropout linear regulators
(LDOs), a reset output, and two N-Channel open
drain switches. An I2C Serial Interface is utilized to
provide programmable LDO and battery charger
functionality.
• Charger Current Monitor Output
• Six Low Noise LDOs
− 3.00V at 250mA
− 1.80V at 150mA
− 3.00V at 80mA
− 3.00V at 80mA
− 3.00V at 80mA
− 3.00V at 150mA
− Programmable LDO Output Voltages
The ACT5810 features six low-noise LDOs and are
divided into two sets of three: one set optimized for
minimum quiescent supply current, and the other
optimized for high PSRR, achieving more than
60dB PSRR at frequencies up to 10kHz. All LDO
output voltages may be programmed as well as enabled and disabled via the I2C interface.
• Two N-channel Open Drain Switches
• I2CTM Compatible Serial Interface
− Configurable Operating Modes
The charger is a complete, thermally-regulated,
stand-alone single-cell linear mode charger for Li+
batteries. It incorporates an internal power MOSFET for constant-current/constant-voltage control.
The battery regulation voltage has 0.5% accuracy,
and features programmable charger currents in the
90mA to 1A range as well as a variety of other functions including a complete charge-management
state machine and charge safety timers.
• AC OK (nACOK) and RESET (nRST) Outputs
• 5×5mm, QFN (QFN55-32) Package
− RoHS Compliant
APPLICATIONS
• GSM or CDMA Mobile Phones
