This datasheet details the specifications and characteristics of the Analog Devices ADP3522, a multifunction power system chip optimized for GSM/GPRS handsets.
The ADP3522 is a multifunction power management system chip designed specifically for GSM/GPRS handsets. It integrates six Low Dropout (LDO) regulators to power critical GSM subblocks and includes features such as Li-Ion battery charge control, optimized for the Analog Devices AD20msp430 baseband chipset.
The device is available in a reduced 5 mm x 5 mm LFCSP-32 package with an exposed die attached paddle for excellent thermal performance. It operates over a temperature range of –20°C to +85 °C and provides sophisticated controls for power-up sequencing, keypad interface, and RTC alarms.
| Operating Ambient Temperature Range | -20°C to +85°C |
|---|---|
| Maximum Junction Temperature | 125°C |
| Package Type | LFCSP-32 (5 mm x 5 mm) |
| Number of LDOs | 6 |
| UVLO ON Threshold (Rising Edge) | 3.2 V to 3.3 V |
| Thermal Shutdown Threshold | 160°C |
The ADP3522 is a multifunction power system chip optimized for GSM/GPRS handsets, especially those based on the Analog Devices AD20msp430 system solution.
A 2.2 µF output capacitor is typically required for stability on the SIM, Digital Core, Analog, and Memory LDOs.
