2.1.6 Protection Circuits

Protection circuits inside the power supply cause only the power supply’s main outputs to shut

down. If the power supply latches off due to a protection circuit tripping, an AC cycle OFF for 15

seconds and a PSON# cycle HIGH for 1 second resets the power supply.

2.1.7 Current Limit (OCP)

The power supply has a current limit to prevent the +3.3V, +5V, and +12V outputs from

exceeding the values shown in the following table. If the current limits are exceeded, the power

supply shuts down and latches off. The latch is cleared by either toggling the PSON# signal or

by an AC power interruption. The power supply is not damaged from repeated power cycling in

this condition. -12 V and 5 VSB are protected under over current or shorted conditions so no

damage occurs to the power supply. 5 VSB will auto-recover after the OCP limit is removed.
