Over-temperature Protection (OTP)
The power supply will be 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 shall
automatically restore power, while the 5 VSB remains always on. The OTP circuit must have
built in hysteresis such that the power supply will not oscillate on and off due to temperature
recovering condition. The OTP trip level shall have a minimum of 4 C of ambient temperature
hysteresis.
