multi-state (2 stage) Li-Ion battery charger
(Constant current / Constant voltage) that
can supply up to 2A of charging current into
a single cell Li-Ion battery.
performance USB battery charger.
LX2201 features a 2A high charge current,
with automatic power savings using isolated
battery topology, user programmability in
USB charging, and an extended battery life
with low Rds
advantages over competition chargers with
the USB Limit Control circuit and low

integrated battery charger solution. . It only
requires three external resistors: one for
setting the constant charge current level, one
for setting the termination charge current,
and one for setting V
in thermostat that will throttle back the
charge current to keep the die temperature
from exceeding 150°C; this feature insures
the LX2201 delivers the maximum charge
rate for a given thermal environment.

features low drop out voltage while providing
an inherent load disconnect with virtually no
drain on the battery when disabled or when
the input power is removed. Additionally a
battery load disconnect switch has been
integrated which provides seamless power
switching when transitioning between charge
