Description

The LTM®8062/LTM8062A are complete 32VIN, 2A μModule® (power module) power tracking battery chargers. The LTM8062/ LTM8062A provide a constant-current/constant-voltage charge characteristic, a 2A maximum charge current, and employ a 3.3V float voltage feedback reference, so any desired battery float voltage up to 14.4V for the LTM8062 and up to 18.8V for the LTM8062A can be programmed with a resistor divider.

The LTM8062/LTM8062A employ 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 LTM8062/LTM8062A are powered by a solar panel, this input regulation loop is used to maintain the panel at peak output power. The LTM8062/LTM8062A also feature preconditioning trickle charge, bad battery detection, a choice of termination schemes and automatic restart.

The LTM8062/LTM8062A are packaged in a thermally enhanced, compact (9mm × 15mm × 4.32mm) over-molded land grid array (LGA) package suitable for automated assembly by standard surface mount equipment. The LTM8062/LTM8062A are RoHS compliant.
