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.
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.
The LP3910 is available in a thermally-enhanced
6-mm × 6-mm × 0.8-mm 48-pin WQFN package.
