DESCRIPTION
The LT®3652 is a complete monolithic step-down battery charger that operates over a 4.95V to 32V input voltage range. 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 oat voltage feedback reference, so any desired battery oat voltage up to 14.4V can be programmed with a resistor divider. The LT3652 employs an input voltage regulation loop, which reduces charge current if the input voltage falls below a programmed level, set with a resistor divider. When the LT3652 is powered by a solar panel, the input regulation loop is used to maintain the panel at peak output power. The LT3652 can be con gured to terminate charging when charge current falls below 1, 10 of the programmed maximum (C, 10). Once charging is terminated, the LT3652 enters a low-current (85μA) sta.
