General Description

The APL3573A is designed for desktop adapter applications. The low on resistance N-channel MOSFET power

switch can satisfy the voltage drop requirements of USB

specification.

The protection features include OCP protection, short circuit protection, over-temperature protection, input under

voltage protection, input surge protection.

Other features include a deglitched ACOK output to indicate the fault condition and an enable input to enable or

disable the device.
