The uP7501 is a power switch controller specifically designed to provide the 5VDUAL voltage for modern motherboards. It controls the switches to power the 5VDUAL plane to comply with ACPI specifications for implementing Sleep States. It switches the ATX/BTX 5VCC output through an NMOS transistor during active states, or switches the ATX/BTX 5VSB through a PMOS transistor for S3 sleep state. A MODE pin controls the power on/ shut down of the 5VDUAL rails during the S4/S5 states. A soft start fun.
