Product Overview

The LT3652EDD#PBF is a Power Tracking Battery Charger for solar power 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. It 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 configured 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) standby mode. An auto-recharge feature starts a new charging cycle if the battery voltage falls 2.5% below the programmed float voltage.
  • Input supply voltage regulation loop for peak power tracking in (MPPT) solar applications
  • Wide input voltage range (4.95 to 32V, 40V absolute maximum)
  • Up to 2A programmable charge current
  • User selectable termination (C/10 or on-board termination timer)
  • Resistor programmable float voltage up to 14.4V
  • 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
