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.

Note 1: Thermal properties are specified with product mounted on PC board with one square-inch of copper area and still air.
Note 2: This device is constructed using a unique set of packaging techniques that impose a limit on the termal profile the device can be
exposed to during solder attach and rework. This limit permits only the use of the solder profiles recommended in the industry stan-
dard specification, IPC/JEDEC J-STD-020A, paragraph 7.6, Table 3 for the IR/VPR and Convention reflow. Pre-heating is required.
Hand or wave soldering is not allowed.
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
