General Description
The APL3203A/B/C provide complete Li+ charger protec-
tions against over-voltage, over-current, and battery over-
voltage. The IC is designed to monitor input voltage, in-
put current, and battery voltage. When any of the moni-
tored parameters are over the threshold, the IC removes
the power from the charging system by turning off an in-
ternal switch. All protections also have deglitch time
against false triggering due to voltage spikes or current
transients. The APL3203A/B/C also provide over-tempera-
ture protection, a FAULT output pin to indicate the fault
conditions, and the EN pin to allow the system to disable
the IC.

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).
