LTM8062/LTM8062A
32VIN, 2A µModule Power
Tracking Battery Chargers
Description
The LTM®8062/LTM8062A are complete 32VIN, 2A
µModule® 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 regula-
tion loop, which reduces charge current if the input volt-
age 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 en-
hanced, 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.
