Description
General part information
LP3923 Series
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-voltage-protection (OVP), one Buck regulator, 8 low-noise low-dropout (LDO) voltage regulators, and a high-speed serial interface to program on/off conditions and output voltages of individual regulators, and to read status information of the PMU. Two LILO (low-input, low-output) type LDOs with separate power input provide an application option for pre-regulated high efficient power management for longer battery life.
The Li-Ion charger can safely charge and maintain a single cell Li-Ion battery operating from an AC adapter. The charger integrates a power FET, a reverse current blocking diode, a sense resistor with current monitor output, and requires only a few external components. Charging is thermally regulated to obtain the most efficient charging rate for a given ambient temperature.
