Solar Charger Ic Lt3652

The lt3652 provides a constant current constant voltage charge characteristic with maximum charge current externally programmable up to 2a.

Solar charger ic lt3652. Linear technology has released the the lt3652 an innovative solar power directed monolithic buck battery charger ic for modern battery chemistries. Meeting this need is linear technology s lt3652 monolithic buck charger ic which operates with a single solar panel. The lt3652 provides a constant current constant voltage charge characteristic with maximum charge current externally programmable up to 2a. For long periods of time requiring a charger that can properly operate a solar panel.

Once charging is terminated the lt3652 enters a low current 85μa standby mode. Lt introduces a new 2a solar battery charger ic when the lt3652 is connected to a solar panel the input regulation loop maintains the panel at peak output power. The lt3652 can be configured to terminate charging when charge current falls below 1 10 of the programmed maximum c 10. Charger for solar power the lt 3652 is a complete monolithic step down bat tery charger that operates over a 4 95v to 32v input voltage range.
