4.1.4.3 Over-temperature Protection (OTP)
The power supply is protected against over-temperature conditions caused by loss of fan
cooling, excessive ambient temperature, or excessive loading. Sensing points are placed at hot
spots. In an OTP condition, the power supply shuts down. When the power supply temperature
drops to within specified limits, the power supply restores power automatically, while the 5VSB
always remains on. The OTP circuit has built-in hysteresis such that the power supply does not
oscillate on and off due to temperature recovery conditions. The OTP trip level has a minimum
of 4° Celsius of ambient temperature hysteresis.

Control and Indicator Functions

The following sections define the input and output signals from the power supply. Signals that
can be defined as low true use the following convention:
signal# = low true
4.1.5.1 PSON# Input Signal
#
The PSON signal is required to remotely turn on/off the power supply. PSON
signal that turns on the +12V power rail. When this signal is not pulled low by the system or left
open, the outputs (except for the +5VSB) turn off. This signal is pulled to a standby voltage by a
pull-up resistor internal to the power supply.
