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 a user programmable trickle charge current to compensate for self discharge losses in the backup cell. The LTC1558's automatic backup switching architecture requires minimum intervention from the host system and provides feedback to the host to minimize system loading in the backup state. Its intern
