General Description
The APL3520 series of power switches are designed for
USB applications. The 70mΩ N-channel MOSFET power
switch satisfies the voltage drop requirements of USB
specification.
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, and when V
OUT
drops below 1.5V, the devices
limit the current to a lower and safe level. The OTP limits
the junction temperature below 140
o
C in case of short
circuit or over load conditions.
Other features include deglitched OCBx output to indi-
cate the fault condition and ENx input to turn on or turn off
output.

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).

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.
