General Description
The APL3209 is a constant-current/constant-voltage lin-
ear charger for single cell Li+ batteries. The APL3209
needs no external MOSFETs or diodes, and accepts in-
put voltage up to 6.5V.
On-chip thermal regulation protects the APL3209 from
excessive temperature, and optimizes the board design
for compact size and typical thermal conditions. The
APL3209 monitors the ambient or battery temperature
and maximum charge time, the charge will stop and indi-
cate a fault when the temperature is out of range or the
charge time is longer than the limit. Charge current can
program by connecting an external resistor from IREF to
GND.
Other features include a STATUS output to indicate the
charge states, and a FAULT output to indicate the fault
conditions. An EN input switches the charger on or off.
The APL3209 is available in a DFN3x3-10 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-020D 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).
