High-Side Power Protection Switches
The APL3522A/B is a power-distribution switch with some
protection functions that can deliver current up to 2.5A.
The device incorporates a 60mN-channel MOSFET
power switch that is controlled by an enable logic pin and
dedicated to soft-start ramp-up rate control that can be
used in application where the inrush current is concerned.
It can be programmable VOUT discharge function by DIS
pin.
The device integrates some protection features, includ-
ing current-limit protection, short-circuit protection, over-
temperature protection, and UVLO. The current-limit and
short-circuit protection can protect down-stream devices
from catastrophic failure by limiting the output current at
current-limit threshold during over-load or short-circuit
events. When VOUT drops below VIN-1.5V the devices limit
the current to a lower and safe level. The over-tempera-
ture protection function shuts down the N-channel
MOSFET power switch when the junction temperature
rises beyond 140oC and will automatically turns on the
power switch when the temperature drops by 20oC. The
UVLO function keeps the power switch in off state until
there is a valid input voltage present.
The device is available in lead free SOT-23-5 packages
with enable active-high(EN) and active-low(ENB) versions.

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).

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.
