4 / 12 page ADM9264 –4– REV. 0 PIN FUNCTION DESCRIPTIONS Pin No. Mnemonic Function 1 GND Ground. 2 SU1 Supply to Be Monitored. 12 V ± 6%. 3 SU2 Supply to Be Monitored. 5 V ± 7%. 4 SU3 Supply to Be Monitored. 3.3 V ± 7%. 5 SU4 Supply to Be Monitored. 2.8 V ± 5%. 6 NC No Connect. 7 ERRX Digital Input. Auxiliary error input (active high). When High it forces PWROK to be Low. 8VCC 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). 9 SU4DET Digital Input. Disable SU4. When High it causes ERR4 to pull high through 10 k Ω external resistor to a positive power supply. 10 ERRY Digital Input. Auxiliary error input (active low). When Low it forces PWROK to be Low. 11 DIS Digital Input. When High it forces PWROK to be High. 12 ERR4 Open Drain Output. Pulls high through 10 k Ω external resistor to a positive power supply when SU4DET is high or SU4 is within its required tolerance of 2.8 V ± 5%. Pulls Low otherwise. 13 ERR3 Open Drain Output. Low when SU3 is outside its required tolerance of 3.3 V ± 7%. Pulls High other- wise through 10 k Ω external resistor to a positive power supply. 14 PWROK Open Drain Output. Pulls High through external 10 k Ω 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. 15 ERR2 Open Drain Output. Low when SU2 is outside its required tolerance of 5 V ± 7%. Pulls High other- wise through 10 k Ω external resistor to a positive power supply. 16 ERR1 Open Drain Output. Low when SU1 is outside its required tolerance of 12 V ± 6%. Pulls High other- wise through 10 k Ω external resistor to a positive power supply.
