Check for Samples: LP3919 DESCRIPTION
The LP3919 is a complete Power Management Unit (PMU) designed for CDMA cellular phones. The LP3919
PMU contains a Li-Ion battery charger, low-noise low-dropout voltage regulators, buck regulators, a USB
Transceiver, comparators 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.
These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam
during storage or handling to prevent electrostatic damage to the MOS gates. System Diagram Li-Ion Charger AC Adapter ADC 2 x DC/DC BB Processor
