CDMA Power Management Unit

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.
