The APL3546 is a power-distribution switch with some
protection functions that can deliver current up to 2.5A.
The device incorporates a 78mΩ N-channel MOSFET
power switch that is controlled by an enable logic pin and
has a SS pin dedicated to soft start ramp-up rate control
that can be used in application where the inrush current
is concerned.
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 V -1V the devices limit
IN
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 150oC 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.
