GENERAL DESCRIPTION

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.
