General Description
The APL3227E overvoltage protection devices feature a
low 50m(max) RON internal FET and protect low-volt-
age systems against voltage faults up to +28VDC. An
internal clamp also protects the devices from surge up to
+120V. When the input voltage exceeds the overvoltage
threshold, the internal FET is turned off to prevent dam-
age to the protected downstream components.
The overvoltage protection threshold can be adjusted with
optional external resistors to any voltage between 4V and
20V. With the OVLO input set below the external OVLO
select voltage, the APL3227E automatically choose the
accurate internal trip thresholds. The internal overvoltage
thresholds (OVLO) are preset to 13.32V typical. The de-
vices feature an open-drain ACOK output indicating a
stable supply between minimum supply voltage and
VOVLO. The APL3227E are also protected against over
current events by an internal thermal shutdown.

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 Greento 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).
