Fault#
I_ts
System Fault Input Signal.
Pull the pin low when any critical event alerted; the chip
will shut the system down when the signal pulled low.
6 PS_ON_IN# I_ts
7 PS_ON_OUT# OD₁₂
ATX PS_ON# Signal Input.
The PS_ON# signal of ATX power supply is routed through
the chip for power fault control.
