Q4
If a P-Channel MOSFET is used to switch the 5VSB output
of the ATX supply into the 5V
S4/S5 states (as dictated by EN5VDL status), then, similar
to the situation where Q1 is a MOSFET, the selection criteria
of this device is also proper voltage budgeting. The

4.5V of V
If a PNP device is chosen to perform this function, it has to
have a low saturation voltage while providing the maximum
sleep-state current and have a current gain sufficiently high
to be saturated using the minimum drive current (typically
20mA; 4mA during soft-start).

The two N-Channel MOSFETs are used to switch the 3.3V
and 5V inputs provided by the ATX supply into the
3.3VDUAL and 5VDUAL outputs, respectively, while in active
(S0, S1) states. Similar r
