uP7501 Overview
Features 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 ply 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.
