SOT23, Single-Cell Li+ Battery

Charger for Current-Limited Supply

General Description

Features

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.

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

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.

o Safely Precharges Near-Dead Cells

o Automatic Power-Down when Input Power

Removed

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.
