ADP3408ARU-1.8 - Analog IC
Overview
The ADP3408 is a multifunctional power system optimized chip for GSM handsets, especially those in the analog base AD20msp430 system solution. It contains six LDOs, one to the critical GSM power block each. Sophisticated controls are used to power rechargeable batteries when registering, keyboard interface, RTC alarm clock. The charging circuit maintains the initial charging phase of the low-current charging process and provides an end-of-charge signal when the Li-Ion battery is charging. The ADP3408 is specified over the -20°C to +85°C temperature range and is available in a narrow TSSOP -28-pin package.
Features handle all GSM baseband power management LDOs optimized for specific GSM six subsystems
