Thermal Specifications and Design Considerations
consumption. Bi-directional PROCHOT# can allow VR thermal designs to target
maximum sustained current instead of maximum current. Systems should still provide
proper cooling for the VR and rely on bi-directional PROCHOT# only as a backup in
case of system cooling failure. The system thermal design should allow the power
delivery circuitry to operate within its temperature specification even while the
processor is operating at its TDP. With a properly designed and characterized thermal
solution, it is anticipated that bi-directional PROCHOT# would only be asserted for
very short periods of time when running the most power intensive applications. An
under-designed thermal solution that is not able to prevent excessive assertion of
PROCHOT# in the anticipated ambient environment may cause a noticeable
performance loss.
