SOT23, Single-Cell Li+ Battery
Charger for Current-Limited Supply
General Description
The MAX1736 is a simple, low-cost, single-cell lithium-
ion (Li+) battery charger for small hand-held applica-
tions. When accompanied by a current-limited voltage
source (such as a wall cube), the MAX1736 provides
simple, accurate charging and termination control for
single-cell Li+ batteries. The MAX1736EUT42 is preset
to a 4.2V battery regulation voltage, while the
MAX1736EUT41 is preset to 4.1V.
The MAX1736 initiates charging in one of four ways:
battery insertion, charger power-up, battery voltage
threshold, and by external manipulation of the EN pin.
The device features an internal precharge current
source that safely charges near-dead cells, as well as
input-supply detection that shuts down the MAX1736
when the supply is removed to minimize battery current
drain.
The MAX1736 accepts input voltages up to 22V, mak-
ing it compatible with a wide range of input supplies. It
has a single control input yet offers stand-alone and
microprocessor-controlled operation. The MAX1736 is
packaged in a small SOT23-6 package. An evaluation
kit (EV kit) is available to reduce design time.
Features
o Small 6-Pin SOT23 Package
o Stand-Alone or μP-Controlled Operation
o 0.5% Voltage Set-Point Accuracy
o Lowest Power Dissipation
o Low 4.7V min Input Voltage
o Top-Off Charging to Achieve Full Battery Capacity
o No Inductor Required
o Safely Precharges Near-Dead Cells
o Automatic Power-Down when Input Power
Removed
