3GS
Low indicates channel 3 gate is driven on (VGATE > VIN + 1.75 V).
12BS
This bit goes high when the 12-V ORing logic commands the BLK pin high ( 25 V ) and the BLK FET should be on.
12PS
This bit goes low when the 12-V PASS pin is above the timer start threshold (OUT12 + 7 V), indicating that the 12-V PASS
FET should be on.
3BS
This bit goes low when the 3 V ORing logic commands the 3 V pass FET on, indicating that a reverse blocking condition does
not exist.
3GS
This bit goes low when the 3 V FET gate-to-source voltage exceeds 1.75 V, indicating that the 3 V FET should be on.
