LTC3559/LTC3559-1
TYPICAL APPLICATIONS
The Battery Can be Charged with Up to 950mA of Charge Current. Buck Regulator 2 Is Enabled Only After V OUT1 Is Up to Approximately
0.7V. This Provides a Sequencing Function Which May Be Desirable in Applications Where a Microprocessor Needs to Be Powered Up
Before Peripherals. CHRG Interfaces to a Microprocessor Which Decodes the Battery Charger State
