GENERAL DESCRIPTION
The ADP3510 is a multifunction power system chip optimized for CDMA handset power management. It contains six specialized LDOs, one to power each of the critical CDMA subblocks. Sophisticated controls are available for power-up during battery charging, keypad interface, and RTC alarm. If a Li-Ion battery is being charged, the charge circuit maintains low current charging during the initial charge phase and provides an end of charge (EOC) signal when the cell has been fully charged.
The ADP3510 is specified over the temperature range of –20°C to +85°C and is available in a narrow body TSSOP 28-Lead package.
