2.5.9 

Protection Circuits 

Protection circuits inside the power supply cause only the power supply’s main outputs to 
shutdown. If the power supply latches off due to a protection circuit tripping, an AC cycle OFF 
for 15 sec and a PSON# cycle HIGH for 1 sec will reset the power supply. 

2.5.9.1 

Over-current Protection (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 will shut down and latch off. The latch will be cleared by toggling the PSON

#

 signal or by 

an AC power interruption. The power supply will not be damaged from repeated power cycling 
in this condition. -12V and 5VSB are protected under over-current or shorted conditions so that 
no damage can occur to the power supply. The 5VSB will auto recover after removing the OCP 
limit.
