DESCRIPTION
The LTC®1559 is a backup battery controller that provides all the functions necessary to implement a backup 3.
3V or 5V power supply using a single NiCd cell.
It includes a 1.
2V to 3.
07V/4.
63V boost converter, an intelligent 2-stage battery charger, automatic backup switching and a microprocessor reset generator.
The boost converter uses a synchronous switching architecture to achieve a typical efficiency of 70%, ensuring maximum backup lifetime from a small NiCd cell.
The on-chip NiCd charger uses an internal gas gauge to minimize fast recharge time and prevent overcharging of the backup cell, thereby...
