3.1.7.1 Over Voltage Protection (OVP)
The power supply over voltage protection is locally sensed. The power supply will shut down
and latch off after an over voltage condition occurs. This latch can be cleared by toggling the
#
PSON signal or by an AC power interruption. The following table contains the over voltage
limits. The values are measured at the output of the power supply's pins. The voltage never
exceeds the maximum levels when measured at the power pins of the power supply connector
during any single point of fail. The voltage will not trip any lower than the minimum levels when
measured at the power pins of the power supply connector. +5VSB will auto-recover after the
OVP condition is removed.
3.1.7.2 Over Temperature Protection (OTP)
The power supply is protected against over temperature conditions caused by loss of fan
cooling or excessive ambient temperature. In an OTP condition, the power supply will shut
down. When the power supply temperature drops to within specified limits, the power supply will
restore power automatically, while the 5VSB will always remain on. The OTP circuit has a built-
in hysteresis such that the power supply will not oscillate on and off due to a temperature
recovering condition. The OTP trip level has a minimum of 4°C of ambient temperature
hysteresis.
