Charger
with Overvoltage Protection
DESCRIPTION
The LTC
®
4098-3.6 is a high efficiency USB PowerPath
controller and full-featured LiFePO
4
battery charger. It seam-
lessly manages power distribution from multiple sources
including USB, wall adapter, automotive, Firewire or other
high voltage DC/DC converters, and a LiFePO
4
battery.
The LTC4098-3.6 charge algorithm is optimized for LiFePO
4
by implementing a 1-hour float voltage termination timer
and a 0°C to 60°C NTC-based charge qualification range.
Furthermore, completely discharged batteries are charged
at the full programmed charge current.
The LTC4098-3.6’s switching regulator can automatically
limit its input current for USB compatibility. For automo-
tive and other high voltage applications, the LTC4098-3.6
interfaces with an external switching regulator. Both the
USB input and the auxiliary input controller feature Bat-
Track optimized charging to provide maximum power to
the application and reduced heat in high power density ap-
plications with input supplies from 5V to as high as 38V.
An overvoltage protection circuit guards the LTC4098-3.6
from high voltage damage on the VBUS pin with just two
external components.
The LTC4098-3.6 is available in a 20-lead 3mm
