FEATURES
Handles all GSM Baseband Power Management
Six LDOs Optimized for Specific GSM Subsystems
Li-Ion and NiMH Battery Charge Function
Optimized for the AD20msp430 Baseband Chipset
APPLICATIONS
GSM/DCS/PCS/CDMA Handsets
GENERAL DESCRIPTION
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 –20
°
C to
+85
°
C and is available in narrow body TSSOP-28 pin package.
