General Description
The APL3518/9 series of power switches are designed
for USB applications. The 62mΩ N-channel MOSFET
power switch satisfies the voltage drop requirements of
USB specification.
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
OUT
drops below 1.5V, the devices limit
the current to a lower and safe level. The over-tempera-
ture protection limits the junction temperature below
140
o
C in case of short circuit or over load conditions.
Other features include a deglitched OCB output to indi-
cate the fault condition and an enable input to enable or
disable the device.
