Function
Ground.
Supply to Be Monitored. 12 V
Supply to Be Monitored. 5 V
Supply to Be Monitored. 3.3 V
Supply to Be Monitored. 2.8 V
No Connect.
Digital Input. Auxiliary error input (active high). When High it forces PWROK to be Low.
Supply Monitor IC Power Supply. Can be powered off any power supply between 2.5 V and 6 V
including one of the supplies being monitored (except for SU1).
Digital Input. Disable SU4. When High it causes ERR4 to pull high through 10 k external resistor to
a positive power supply.
Digital Input. Auxiliary error input (active low). When Low it forces PWROK to be Low.
Digital Input. When High it forces PWROK to be High.
Open Drain Output. Pulls high through 10 k external resistor to a positive power supply when
SU4DET is high or SU4 is within its required tolerance of 2.8 V
Open Drain Output. Low when SU3 is outside its required tolerance of 3.3 V
wise through 10 k external resistor to a positive power supply.
Open Drain Output. Pulls High through external 10 k resistor to a positive power supply when SU1,
SU2, SU3 and SU4 are all within their required tolerances and when ERRY is High and when ERRX
is Low. Pulls Low otherwise.
Open Drain Output. Low when SU2 is outside its required tolerance of 5 V
wise through 10 k external resistor to a positive power supply.
Open Drain Output. Low when SU1 is outside its required tolerance of 12 V
wise through 10 k external resistor to a positive power supply.
