Short Circuit Protection (SCP) (Required)

An output short circuit is defined as any output impedance of less than 0.1 Ohm. The power supply shall shut down and latch off for shorting +12V DC rails to return. The +12V1 DC and 12V2 DC should have separate short circuit and over current protection. Shorts between main output rails and +12VSB shall not cause any damage to the power supply. The power supply shall either shut down and latch off or fold back for shorting the negative rails. +12VSB must be capable of being shorted indefinitely. When the short is removed, it is recommended that the power supply shall recover automatically or by cycling PS_​ON#. Optionally, the power supply may latch off when a +12VSB short circuit event occurs. The power supply should withstand a continuous short circuit to the output without damage or overstress to the unit (for example, to components, PCB traces, and connectors) under the input conditions specified in Table 4-1.
