Overview
LTC1558-3.
3/LTC1558-5 Backup Battery Controller with Programmable Output FEATURES s s DESCRIPTION The LTC®1558 is a backup battery controller that provides all the functions necessary to implement a backup power supply using a single NiCd cell.
It includes a 1.
2V 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.
The LTC1558 also provides...
