• High-side Power Protection Switches
The APL3546A is a power-distribution switch with some
protection functions. 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, over-temperature protection,
UVLO and current limit setting. The current limit protec-
tion can protect down-stream devices from catastrophic
failure by limiting the output current at current limit thresh-
old during over-load or short circuit events. The over-tem-
perature protection function shuts down IC when the junc-
tion temperature rises beyond 150oC. The UVLO function
keeps the power switch in off state until there is a valid
input voltage present. The current limit can be set by con-
necting resistor from the current limit adjustable pin ISET
to ground.
