General Description
The APL3201 is a constant-current/constant-voltage
linear charger for single cell Li+ batteries.
The APL3201 needs no external MOSFET or diodes, and
accepts input voltage up to 6.0V. The small packages
and low external component count make the APL3201
ideally suited for portable applications.
On-chip thermal limiting simplifies PC board layout and
allows optimum charging rate without the thermal limits
imposed by worst-case battery and input voltage. When
the APL3201 thermal limit is reached, the charger does
not shut down but simply reduces charging current.
Ambient or battery temperature can be monitored with
an external thermistor. When the temperature is out of
range, charging pauses.
Other features include the STAT1 and 2 outputs to indi-
cate four charge states, and the EN input, switches the
APL3201 on or off.
The APL3201 is available in 3mmx3mm DFN-10 package,
and operates over the -40°C to +85°C temperature range.

Note: ANPEC lead-free products contain molding compounds/die attach materials and 100% matte tin plate termination finish; which
are fully compliant with RoHS. ANPEC lead-free products meet or exceed the lead-free requirements of IPC/JEDEC J-STD-020C for
MSL classification at lead-free peak reflow temperature. ANPEC defines “Green” to mean lead-free (RoHS compliant) and halogen
free (Br or Cl does not exceed 900ppm by weight in homogeneous material and total of Br and Cl does not exceed 1500ppm by
weight).
