General Description
The APL3534/A/B is a power-distribution switch with cur-
rent- limiting function and output OVP protections that can
deliver current up to 1A. The device incorporates a 110mΩ
N-channel MOSFET power switch.
The device integrates some protection features, includ-
ing current-limit protection, output over-voltage protection,
over-temperature protection and UVLO. The current-limit
protection can protect down-stream devices from cata-
strophic failure by limiting the output current at current-
limit threshold during over-load or short-circuit events.
The output over-voltage protection can prevent current
flowing from VOUT to VIN when an abnormally high volt-
age exists in VOUT. The over-temperature protection func-
tion shuts down the N-channel MOSFET power switch
when the junction temperature rises beyond 140 C and
will automatically turns on the power switch when the

temperature drops by 20 C. 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-23-3 and
SOT-23-5 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 “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).
