General Description
The APL3550/1 series of power switches integrate a
70mN-channel MOSFET power switch, an enable in-
put pin, a fault flag and some protection functions into a
single package.
The protection features include current-limit protection,
short-circuit protection, and over-temperature protection.
The device limits the output current at current limit thresh-
old level. When V drops below V -1V, the devices limit
OUT
IN
the current to a lower and safe level. The over-tempera-
ture protection limits the junction temperature below
140oC in case of short circuit or over load conditions.
Other features include a deglitched OCB output to indi-
cate the fault condition and an enable input to enable or
disable the device.

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).

Note1: Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are
stress ratings only and functional operation of the device at these or any other conditions beyond those indicated under "recom-
mended operating conditions" is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device
reliability.
