LP3910 Power Management IC for Hard-Drive-Based Portable Media Players

1 Features

2 Applications

•

Two Low-Dropout Regulators With Programmable

Output Voltages:

•

Hard Drive-Based Media Players

Portable Gaming Players

–

LDO1 for General Purpose Applications

LDO2 for Low-Noise Analog Applications

3 Description

•

Green and Red LED-Charger Status Drivers

4-Channel 8-Bit Dual Slope

Analog-to-Digital (ADC) Converter

The LP3910 is a programmable system power

management unit optimized for HDD-based portable

media players. The device incorporates two low-

dropout LDO voltage regulators, two integrated buck

DC-DC converters with dynamic voltage scaling

(DVS), one wide load-range buck-boost DC-DC

converter with programmable output voltage, a 4-

channel, 8-bit ADC, and a dual-source lithium-ion or

lithium-polymer battery charger.

•

2 High-Efficiency DVS Buck Converters

Wide Load Range Buck-Boost DC-DC Converter

400-kHz I²C-Compatible Interface

Linear Constant-Current and Constant-Voltage

Charger for Single-Cell Lithium-Ion Batteries

•

USB and Adapter Charging

The LP3910 also incorporates some advanced

battery management functions such as battery

temperature measurement, reverse current blocking

for USB, LED-charger status indication, thermally

regulated internal power FETs, battery-voltage

monitoring, overcurrent protection, and a 10-hour

safety timer. The device is programmable through a

400-kHz I2C-compatible interface.

System Power Supply Management

Voltage and Thermal Supervisory Circuits

Continuous Battery Voltage Monitoring
