13 RESERVED Digital Input Connect to GND.
14 GND Power Ground reference pin for the power supply voltage.
The state of this pin determines whether the CO1-CO6 pins are active
15 COPOL Digital Input “HIGH” or “LOW”. When tied LOW the CO1-CO6 outputs will go LOW to
indicate an out of window comparison.
The state of this pin determines whether the AO pin is active on an over-
16 AOSEL Digital Input voltage or under-voltage event. When tied LOW the AO output will be
active upon an over-voltage event.
This output is the ANDED combination of either the over-voltage
Open-Drain NMOS
17 AO comparator outputs or the under-voltage comparator outputs and is
