13.2.6 Protection Circuits
Protection circuits inside the power supply causes 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 15sec and a PSON
#
cycle HIGH for one second, must be able to reset the power supply.
13.2.6.1 Current Limit (OCP)
Below are over current protection limits for each output. 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. -12V and 5VSB is protected under over current or shorted conditions so that no
damage can occur to the power supply. 5Vsb will be auto-recovered after removing OCP limit.
