LT3652 is a complete monolithic step-down battery charger for solar power. This 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, so any desired battery float voltage up to 14.4V can be programmed with a resistor divider. This 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 this is powered by a solar panel, the input regulation loop is used to maintain the panel at peak output power. It can be configured to terminate charging when charge current falls below 1/10 of the programmed maximum (C/10). Typical applications are solar powered applications, remote monitoring stations, LiFePO4 (lithium phosphate) applications, portable handheld instruments, 12V to 24V automotive systems.
• Input supply voltage regulation loop for peak power tracking in (MPPT) solar applications

• User selectable termination is C/10 or on-board termination timer
• No VIN blocking diode required for battery voltages <= 4.2V
• 1MHz fixed frequency, 0.5% float voltage reference accuracy
• 5% charge current accuracy, 2.5% C/10 detection accuracy
• Binary-coded open-collector status pins
• 12-lead plastic MSOP package
• Temperature range from -40°C to 125°C
