GENERAL DESCRIPTION
The ADP3500 is a multifunction power system chip optimized
for CDMA cell phone power management. It contains 15 LDOs.
Sophisticated controls are available for power up during battery
charging, keypad interface, GPIO/INT function and RTC
function. The battery charger has four modes as Pre-charge, Low
Current Charge, Full Current Charge, and Regulator modes, and
is designed for Li-Ion/Li-Polymer batteries.
