The LP3913 is a programmable system power management
unit that is optimized for Flash Memory based Portable Media
Players.
The LP3913 incorporates 2 low-dropout LDO voltage regulators,
3 integrated Buck DC/DC converters with Dynamic Voltage
Scaling (DVS), a 4-channel 8-bit A/D converter, and a
dual source Li-Ion/polymer battery charger. The charger has
the capability to charge and maintain a single cell battery from
a regulated wall adapter or USB power. When both USB and
adapter sources are present, then the adapter source takes
precedence and switching between USB and adapter power
sources is seamless. In addition, the battery charger supports
power routing, which allows system usage immediately after
an external power source has been detected. The LP3913
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, over-current protection and a 10–hour safety
timer.
