DESIGN FEATURES Next Generation No Compromise
by Mark Gurries
Battery Chargers
Introduction
Until now, a fully-featured high power
battery charger simply did not exist
in a single IC. No one had succeeded
in squeezing a charger into a small
package without compromising some
functionality, such as wide voltage
range, current range, accuracy, low
external part count, or efficiency.
For instance, some single-IC chargers focus on the analog PWM power
control side of charging while others
just perform the charge termination
function. None offered it all in one
package, until now.
Linear Technology introduces a
family of complete single-IC high power
battery charger solutions that do not
compromise any functionality for small
IC size. The new LTC4006, LTC4007
and LTC4008 series of battery chargers …

LвЂ‰DESIGN FEATURES Feature-Packed Charger Handles
All Battery Chemistries and Produces
3A/50W for Fast Charging from a
4mm Г— 4mm QFN
by James A. McKenzie
Introduction
The LTC4009, LTC4009-1 and
LTC4009-2 are a family of high power
battery charger ICs that achieve a small
circuit size and high performance without compromising functionality. The
family operates with high efficiency
while packing the most desirable
charging and protection features into
a space-efficient 20-lead 4mm Г— 4mm
QFN package. When combined with
just a few external components and
termination control, the LTC4009
family facilitates construction of
chargers capable of delivering up to
3A to batteries with output power
levels approaching 50W. These ICs are especially well-suited to implementing
microprocessor-controlled chargers
for all chemistry types, including …
