The APL3553G 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 drops below V -1V, the devices limit
