*Stresses above those listed under Absolute Maximum Ratings may cause permanent
  damage to the device. This is a stress rating only; functional operation of the
  device at these or any other conditions above those listed in the operational
  sections of this specification is not implied. Exposure to absolute maximum rating
  conditions for extended periods may affect device reliability. Absolute maximum

The ADP3502 is a multifunction chip optimized for CDMA-1x cell phone power management. It offers a total power solution for the handset baseband and RF section, including LDOs to power 11 subsystems. Also integrated are a real-time clock (RTC), serial bus interface, and charging control for Li-Ion/ Li-Polymer batteries. Sophisticated controls are available for power-up during battery charging, keypad interface, GPIO/INT function, and RTC function.

The ADP3502 is optimized for CDMA handsets powered by single-cell Li-Ion batteries. Its high level of integration significantly reduces the design effort, number of discrete components, and solution size/cost. The main-sub LDO structure reduces the standby current consumption, and as a result, greatly extends the standby time of the phone. System operation has been proven to be fully compatible with MSM51xx-based designs.

The ADP3502 comes in a 64-lead 7 mm * 7 mm * 1 mm TQFP package and is specified over a wide temperature range of 30°C to +85°C.
