DESCRIPTION

35V/3.2A Multicell

LiFePO4 Step-Down Battery Charger

with PowerPath and I2C Telemetry

The LTC®4162-F is an advanced monolithic synchronous

step-down switching battery charger and PowerPath™

manager that seamlessly manages power distribution

between input sources such as wall adapters, backplanes,

solar panels, etc., and a rechargeable lithium iron phos-

phate battery.

A high resolution measurement system provides exten-

sive telemetry information for circuit voltages, currents,

battery resistance and temperature which can all be read

back over the I2C port. The I2C port can also be used to

configure many charging parameters including charging

voltages and currents, termination algorithms and numer-

ous system status alerts.

The LTC4162-F can charge LiFePO4 cell stacks from 1 cell

to 9 cells with as much as 3.2A of charge current.

The power path topology decouples the output voltage

from the battery allowing a portable product to start up

instantly under very low battery voltage conditions.

The LTC4162-F is available in a thermally enhanced 28-

pin 4mm × 5mm × 0.75mm QFN surface mount package.
