产品详情
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.
APPLICATIONS
- GSM/DCS/PCS/CDMA Handsets
