APL3548 is a high-side power distribution switch, allow
for +12V, +19V or +9.5V power-supply rail. The wrong
input voltage protection function protects a wrong input of
adapter insertion, when input voltage is out of the target
input voltage range the IC is off.
The APL3548 provides a short-circuit protection during
power-up. When a short circuit is present before soft start,
the IC will limit the output current at 300mA during dead
short condition (VOUT<1V) unless the short circuit has been
removed and the output voltage has risen above 1V. After
power-up the OCP function prevents the IC from cata-
strophic failure from over-load and short circuit conditions.
If an OC event is detected, the IC immediately shuts down
the internal power switch and will initiate a new soft start
cycle. The OCP tripping threshold is set by the external
resistor on OCSET pin.
Other features include an adjustable soft start time and a
logic-controlled shutdown mode. The device is available
in SOP-8P and TDFN3x3-10 Packages.

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.
