LP3918  
Battery Charge Management and Regulator Unit  
General Description  
Features  
The LP3918 is a fully integrated charger and multi-regulator  
unit designed for CDMA cellular phones. The LP3918 con-  
tains a Li-Ion battery charger, 7 low noise low dropout (LDO)  
voltage regulators and a high-speed serial interface to pro-  
gram on/off conditions and output voltages of individual reg-  
ulators, and also to read status information from the PMU.  
Fully integrated Li-Ion battery charger with thermal  
regulation  
USB Charge Mode.  
7 Low Noise LDO’s  
2 x 300 mA  
3 x 150 mA  
2 x 80 mA  
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.  
I2C compatible interface for controlling LDO outputs and  
charger operation  
Thermal shutdown  
Under Voltage Lockout  
LDO regulators provide high PSRR and low noise ideally suit-  
ed for supplying power to both analog and digital loads.  
25-bump Thin micro-SMD package 2.5 x 2.5 mm  
Options available on request, please contact sales office  
for further information;  
Applications  
- Level detect on HF_PWR & PWR_ON  
- LDO Charging mode  
- Custom Default Settings on Charger, and LDO O/P's.  
CDMA Phone Handsets  
Low Power Wireless Handsets  
Handheld Information Appliances  
Personal Media Players  
Key Specifications  
Digital Cameras  
50mA to 950mA Programmable Charge Current  
3.0V to 5.5V Input Voltage Range  
200mV typ. Dropout Voltage on 300 mA LDO’s  
2% (typ) Output Voltage Accuracy on LDO’s
