Product Summary
The LTC1760CFW is a highly integrated level 3 battery charger and selector intended for products using dual smart batteries. Three SMBus inter-faces allow the LTC1760 to servo to the internal voltageand currents measured by the batteries while allowing an SMBus Host to monitor either battery status. Applications of the LTC1760CFW include: Portable Computers and Instruments, Standalone Dual Smart Battery Chargers and Battery Backup Systems.
