The ADP3522 is a multifunction power system chip optimized for GSM/GPRS handsets, especially those based on the Analog Devices AD20msp430 system solution with 1.8 V digital baseband processors, such as the AD6525, AD6526, and AD6528. It contains six LDOs, one to power each of the critical GSM subblocks. Sophisticated controls are available for powerup 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 (EOC) signal when a Li-Ion battery is being charged. This product also meets the market trend of reduced size with a new LFCSP package. Its footprint is only 5 mm 5 mm and yet offers excellent thermal performance due to the exposed die attached paddle. The ADP3522 is specified over the temperature range of 20C to +85C.
