10 +IN5 Analog Input Positive input for window comparator 5
11 –IN6 Analog Input Negative input for window comparator 6
12 +IN6 Analog Input Positive input for window comparator 6
13 RESERVED Digital Input Connect to GND
14 GND Power Ground reference pin for the power supply voltage
15 COPOL Digital Input The state of this pin determines whether the CO1-CO6 pins are active “HIGH” or “LOW”. When tied LOW the CO1-CO6 outputs go LOW to indicate an out-of-window comparison.
16 AOSEL Digital Input The state of this pin determines whether the AO pin is active on an overvoltage or undervoltage event. When tied LOW the AO output is active upon an overvoltage event.
17 AO Open-Drain NMOS Digital Output This output is the ANDED combination of either the overvoltage comparator outputs or the undervoltage comparator outputs and is controlled by the state of the AOSEL. AO pin is active-low.
18 CO6 Open-Drain NMOS Digital Output Window comparator 6 NMOS open-drain output
19 CO5 Open-Drain NMOS Digital Output Window comparator 5 NMOS open-drain output
20 CO4 Open-Drain NMOS Digital Output Window comparator 4 NMOS open-drain output
21 CO3 Open-Drain NMOS Digital Output Window comparator 3 NMOS open-drain output
22 CO2 Open-Drain NMOS Digital Output Window comparator 2 NMOS open-drain output
23 CO1 Open-Drain NMOS Digital Output Window comparator 1 NMOS open-drain output
