RESERVED

Digital Input

Connect to GND.

GND

Power

Ground reference pin for the power supply voltage.

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.

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.

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”.

CO6

Open-Drain NMOS

Digital Output

Window comparator 6 NMOS open-drain output.

CO5

Open-Drain NMOS

Digital Output

Window comparator 5 NMOS open-drain output.

CO4

Open-Drain NMOS

Digital Output

Window comparator 4 NMOS open-drain output.

CO3

Open-Drain NMOS

Digital Output

Window comparator 3 NMOS open-drain output.

CO2

Open-Drain NMOS

Digital Output

Window comparator 2 NMOS open-drain output.

CO1

Open-Drain NMOS

Digital Output

Window comparator 1 NMOS open-drain output.

V+

Power

Power supply pin.

DAP

Thermal Pad

Die Attach Paddle (DAP) connect to GND.
