General Description
The GS7611 is a power switch controller used to
provide 5VDUAL voltage for modern motherboards.
It controls the switches to provide 5VDUAL. In active
state, ATX/BTX 5VCC provides the output voltage

through an NMOS transistor, in S3 sleep state,
ATX/BTX 5VSB provides the output voltage through
a PMOS transistor. In S4/S5 state, a MODE pin
decides whether 5VDUAL is shut down or stays on.
Soft start function is implemented to limit inrush
current from 5VSB supply.
