General Description
The APL3207 combines a constant-current/constant-volt-
age linear single cell Li+ battery charger with a low drop-
out linear regulator. Both charger and linear regulators
can work independently. The small DFN-10 package and
low external component count make the APL3207 ideally
suit to portable applications.
The charger of APL3207 provides 0.7A charge current
with thermal regulation protection to optimize the board
design for compact size and typical thermal conditions.
When the junction temperature reaches the thermal regu-
lation threshold, the charger does not shut down but sim-
ply reduces the charge current. The charge current can
be programmed by connecting an external resistor from
the ISET pin to the GND. Using an external MOSFET to
disconnect the resistor from the ground shuts down the
charger, and reduces the input current down to 25µA.
The APL3207 also has the STAT pin to indicate charge
status.
The LDO regulator of APL3207 can deliver up to 150mA
current and dropout voltage is only 200mV. The 4µA low
quiescent current makes it ideally suit to battery-power
systems. The LDO regulator also has built-in current limit
and thermal shutdown protection.

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).
