LTC4110 - Battery Backup System Manager

General Description

The LTC®4110 is a complete single chip, high efficiency, flyback battery charge and discharge manager with automatic switchover between the input supply and the backup battery or super capacitor.

The IC provides four modes of operation: battery backup, battery charge, battery calibration and shutdown.

Key Features

  • n Complete Backup Battery Manager for Li-Ion/ Polymer, Lead Acid, NiMH/NiCd Batteries and Super Capacitors n Charge and Discharge Battery with Voltages Above and Below the Input Supply Voltage n “No Heat” Battery Calibration Discharge Using System Load n Automatic Battery Backup with Input Supply Removal Using PowerPath™ Control n Standalone for Li-Ion/Polymer, SLA, and Supercaps n Optional SMBus/I2C Support Allows Battery Capacity Calibration Operation with Host n Over- and Under-Battery Voltag.
