The LP3923 is a fully Integrated Power Management Unit (PMU) designed for CDMA cellular phones.
The LP3923 PMU contains a fully integrated Li-Ion battery charger with power FET and over-voltageprotection (OVP), one Buck regulator, 8 low-noise low-dropout (LDO) voltage regulators, and a highspeed serial interface to program on/off conditions and output voltages of individual regulators, and to read status information of the PMU.
Two LILO (lowinput, low-output) type LDOs with separate power input provide an application option for pre-regulated high efficient power management for longer battery life.
