The ADP3408 is a multifunction power system chip optimized for GSM handsets, especially those based on the Analog Devices AD20msp430 system solution. It contains six LDOs, one to power each of the critical GSM sub-blocks. Sophisticated controls are available for power-up during battery charging, keypad interface, and RTC alarm. The charge circuit maintains low current charging during the initial charge phase and provides an end-of-charge signal when a Li-Ion battery is being charged. The ADP3408 is specified over the temperature range of 20C to +85C and is available in narrow body TSSOP-28 pin package.
