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.
8
VCC
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 kΩ 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
12
ERR4
13
ERR3
Digital Input. When High it forces PWROK to be High.
Open Drain Output. Pulls high through 10 kΩ 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.
Open Drain Output. Low when SU3 is outside its required tolerance of 3.3 V ± 7%. Pulls High other-
wise through 10 kΩ external resistor to a positive power supply.
14
PWROK
15
ERR2
16
ERR1
Open Drain Output. Pulls High through external 10 kΩ 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 ± 7%. Pulls High other-
wise through 10 kΩ external resistor to a positive power supply.
Open Drain Output. Low when SU1 is outside its required tolerance of 12 V ± 6%. Pulls High other-
wise through 10 kΩ external resistor to a positive power supply.
