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 will 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 over-voltage or under-voltage event. When tied LOW

the AO output will be active upon an over-voltage event.

17

AO

Open-Drain NMOS

Digital Output

This output is the ANDED combination of either the over-

voltage comparator outputs or the under-voltage

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.

24

V+

Power

Power supply pin.
