LTC4162-F

35V/3.2A Multicell

LiFePO Step-Down Battery Charger

with PowerPath and I C Telemetry

FEATURES

DESCRIPTION

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.

LiFePO Battery Charger with Termination

Wide Charging Input Voltage Range: 4.5V to 35V

High Efficiency Synchronous Operation

16-Bit Digital Telemetry System Monitors V

Charges 1-9 Lithium Iron Phosphate Cells

Input Undervoltage Charge Current Limit Loop

Input MPPT for Solar Panel Inputs

Input Current Limit Prioritizes System Load Output

Low Loss PowerPath™

Instant-On Operation with Discharged or Missing

Battery

JEITA Temperature Controlled Charging

Pin Compatible with Li-Ion and SLA Versions

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 I C port. The I C port can also be used to

configure many charging parameters including charging

voltagesandcurrents, terminationalgorithmsandnumer-

ous system status alerts.

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

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

APPLICATIONS

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.
