NAME

VCC

GND

FUNCTION

Device Power-Supply Input. Connect to 2.7V to 16V. Bypass VCC to GND with a 0.1µF

capacitor.

Ground

Internal Supply Bypass Input. Connect a 1µF capacitor from ABP to GND. ABP is an

3

3

ABP internally generated voltage powering internal circuits, and supply more than 1mA

additional current to any external circuitry.

4

4

EN

Analog Enable Input. Connect a resistive divider at EN to monitor a voltage.

The EN threshold is 0.5V.

5

5

SET4

Set Monitored Threshold 4 Input. Monitor a voltage by setting the threshold with an external

resistive divider. The SET4 threshold is 0.5V.

6

6

OUT4

Open-Drain Output 4. When the voltage at SET3* is above 0.5V, OUT4 goes high

impedance. OUT4 requires an external pullup resistor and can be pulled up to VCC.

7

7

DISC4

Discharge Pulldown Input 4. During normal operation, DISC4 is high impedance. During a

fault condition or power-down, DISC4 provides an 85mA sink current.

8

8

SET3

Set Monitored Threshold 3 Input. Monitor a voltage by setting the threshold with an external

resistive divider. The SET3 threshold is 0.5V.

9

OUT3

Open-Drain Output 3. When the voltage at SET2* is above 0.5V, OUT3 goes high

impedance. OUT3 requires an external pullup resistor and can be pulled up to VCC.

*This applies to the MAX16051. For the MAX16050, see Table 1 for the output sequence order.
