The APL3573A is designed for desktop adapter applica-
tions. The low on resistance N-channel MOSFET power
switch can satisfy the voltage drop requirements of USB
The protection features include OCP protection, short cir-
cuit protection, over-temperature protection, input under
voltage protection, input surge protection.
Other features include a deglitched ACOK output to indi-
cate the fault condition and an enable input to enable or
disable the device.
