Notes & Conditions
● Overtemperature
protection can be
triggered and the
PSU can shut down
the output only when
the ambient
temperature exceeds
50°C. The recovery
temperature must
have a hysteresis that
is greater than 5°C.
● The temperature
protection threshold
for the air intake
vent of the PSU
should be greater
than 70°C.
● If overtemperature
occurs in MV12
mode, the output
mode is MV6 (even if
PSON12V# is low) at
system service load.
When the internal
component
temperature recovers
to a safe range, the
output mode can
switch back to MV12
only if PSON12V# is
still low. If
overtemperature
occurs in MV6 mode,
the output is shut
down. When the
internal component
temperature recovers
to a safe range, the
PSU recovers and
works in MV6 output
mode (even if
PSON12V# is low).
After recovery, if
PSON12V# is still
low, the PSU switches
to MV12 output
mode. The hysteresis
