LT3650 monolithic single-cell Li-Ion Polymer battery charger
Using the LT3650 monolithic single-cell Li-Ion Polymer battery charger can be designed a simple charger using few electronic parts .
The LT3650 provides a constant-current constant-voltage charge characteristic and maximum charge current externally programmable up to 2A
The LT3650 can be configured to terminate charging when charge current falls to C/10, or one-tenth the programmed maximum current.
After the charging is complete the LT3650 enters a low current (85μA) standby mode.
If the battery voltage drops 2.5% from the float voltage or if a new battery is a new charging cycle is started automatically .
