132 Revision 2.4
10.2.5.1 Current Limit (OCP)
The power supply has current limit to prevent the outputs from exceeding the values shown in
table below. If the current limits are exceeded the power supply shuts down and latches-off.
The latch will be cleared by toggling the PSON# signal or by an AC power interruption. The
power supply is not damaged from repeated power cycling in this condition. 12VSB will be
auto-recovered after removing OCP limit.

10.2.5.2 Over Voltage Protection (OVP)
The power supply over voltage protection is locally sensed. The power supply shuts down and
latches off after an over voltage condition occurs. This latch is cleared by toggling the PSON#
signal or by an AC power interruption. The values are measured at the output of the power
supply’s connectors. The voltage does not exceed the maximum levels when measured at the
power connectors of the power supply connector during any single point of fail. The voltage
does not trip any lower than the minimum levels when measured at the power connector.
12VSB will be auto-recovered after removing OVP limit.

10.2.5.3 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 PSU will shut down. When
the power supply temperature drops to within specified limits, the power supply shall restore
power automatically, while the 12VSB remains always on. The OTP circuit must have built in
margin 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 margin.
10.2.6 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.
