DESIGN IDEAS Decrease Li-Ion Battery Charge
Time with a Monolithic Charger that
by Phil Juang
Prevents Overheating
Introduction
The LTC4054 is a constant-current/
constant-voltage linear battery charger
with an internal power MOSFET in
a tiny ThinSOT package. Most linear
chargers risk temporary, excessive
power dissipation and possible
overheating, but the LTC4054 uses
internal thermal feedback to regulate
the charge current and limit the die
temperature to 120В°C. This feature
allows the designer to program the
LTC4054 to higher charge currents
with the assurance that the LTC4054
will not overheat and damage itself or
other components. This article shows
how to use the LTC4054 to maximize
the thermally regulated charge current
to reduce battery charging times. …
