DESIGN FEATURES New Standalone Linear
Li-Ion Battery Chargers
Introduction
Rechargeable batteries are commonly
used to power portable devices such as
digital cameras, PDAs, mobile phones
and MP3 players. A wall adapter is
the most common source of charging
power, but an increasing number of
applications are tapping into available USB power. The LTC4061 and
LTC4062 are speciп¬Ѓcally designed to
charge single-cell lithium-ion batteries
from either of these sources.
Both devices use constant current/constant voltage algorithms to
deliver up to 1A of charge current
(programmable) with a п¬Ѓnal п¬‚oat voltage accuracy of В±0.35%. They include
an internal P-channel power MOSFET
and thermal regulation circuitry with
no blocking diode or external sense
resistor requiredвЂ”the basic charger
circuit requires only two external
components.
The LTC4061 and LTC4062 include both programmable time and …
