General Description
The APL3522A/B is a power-distribution switch with some
protection functions that can deliver current up to 2.5A.
The device incorporates a 60mΩ N-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-
