Solar charger ic lt3652.

Smart energy harvesting analog devices a major electronic system solution supplier provides a variety of components for design into low power fci smart energy. 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. Power tracking 2a battery charger for solar power online from elcodis view and download lt3652 pdf datasheet pmic battery management specifications. A pdf version of the schematic can be obtained here.

Linear technology has released the the lt3652 an innovative solar power directed monolithic buck battery charger ic for modern battery chemistries. Once charging is terminated the lt3652 enters a low current 85μa standby mode. The lt3652 provides a constant current constant voltage charge characteristic with maximum charge current externally programmable up to 2a. Circuit maker is a free pcb design tool from altium.

This project is based on a linear technology lt3652 power tracking 2a battery charger for solar power. The charger employs a 3 3v fl oat voltage feedback reference. 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. Request liner linear technology lt3652.

The lt3652 provides a constant current constant voltage charge characteristic with maximum charge current externally programmable up to 2a. The charger employs a 3 3v float voltage feedback reference. For long periods of time requiring a charger that can properly operate a solar panel. The lt3652 can be configured to terminate charging when charge current falls below 1 10 of the programmed maximum c 10.

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. Meeting this need is linear technology s lt3652 monolithic buck charger ic which operates with a single solar panel. Lt3652hv demo circuit wall adapter to 5 cell lifepo4 battery charger 19 32v to 18vfloat 1 5a models for the following parts are available in ltspice. The ic uses average current mode control loop architecture to provide constant current constant voltage cc cv charge characteristics.
