5 / 18 page  Pin Descriptions Pin Symbol Type Description 1 -IN1 Analog Input Negative input for window comparator 1. 2 +IN1 Analog Input Positive input for window comparator 1. 3 -IN2 Analog Input Negative input for window comparator 2. 4 +IN2 Analog Input Positive input for window comparator 2. 5 -IN3 Analog Input Negative input for window comparator 3. 6 +IN3 Analog Input Positive input for window comparator 3. 7 -IN4 Analog Input Negative input for window comparator 4. 8 +IN4 Analog Input Positive input for window comparator 4. 9 -IN5 Analog Input Negative input for window comparator 5. 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 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.
