Description
General part information
LP3918 Series
The LP3918 is a fully integrated charger and multi-regulator unit designed for CDMA cellular phones. The LP3918 contains a Li-Ion battery charger, 7 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 also to read status information from the PMU.
The Li-Ion charger integrates a power FET, reverse current blocking diode, 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.
LDO regulators provide high PSRR and low noise ideally suited for supplying power to both analog and digital loads.
