General Description
The APL3513 is a power-distribution switch with some
protection that can deliver current up to 2A. The device
incorporates a 70mΩ N-channel MOSFET power switch
that is controlled by an enable logic pin.
The protection features include current-limit protection,
short-circuit protection, and over-temperature protection.
The device limits the output current at current limit thresh-
old level. When V drops below V -1V, the devices limit

the current to a lower and safer level. The over-tempera-
ture protection limits the junction temperature below
140^oC in case of short circuit or over load conditions.
