GENERAL DESCRIPTION
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 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 (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 ther-
mal performance due to the exposed die attached paddle.
The ADP3522 is specified over the temperature range of
–20
°
C to +85
°
C.
