DC1568A(#2): 2 Cell, 8.2V, 2A Max, Solar

Summary

Demonstration Circuit 1568A is a 2A Monolithic Multi-Chemistry battery charger (Li-Ion/Polymer, LiFePO4, SLA, NiMH/NiCd) for solar power applications featuring the LT3652EDD.

The LT3652 is a complete mid-power Li-Ion battery charger that can operate over a wide input voltage range. The charger employs a 3.3V float voltage feedback reference that allows the battery float voltage to be adjusted up to 14.4V.

The LT3652 has an input voltage regulation loop which reduces charge current if the input falls below a programmed level, set with a resistor divider. The charger is a CC/CV charger with a maximum charge current of 2A. A precondition feature trickle charges a low-voltage battery, and bad battery detection provides a signal if the battery doesn’t respond to preconditioning.
