DescripTion

The LTM^®8062/LTM8062A are complete 32V , 2A

Complete Battery Charger System

Input Supply Voltage Regulation Loop for Peak

µModule^®powertrackingbatterychargers.TheLTM8062/

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.

Power Tracking in MPPT (Maximum Peak Power

Tracking) Solar Applications

Resistor Programmable Float Voltage Up to 14.4V

on the LTM8062 and 18.8V on the LTM8062A

Wide Input Voltage Range: 4.95V to 32V

(40V Abs Max)

9mm × 15mm × 4.32mm LGA Package

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.

applicaTions

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.
