NAME
FUNCTION
17
GPI4
General-Purpose Logic Input 4. An internal 10A current source pulls GPI4 to GND.
Configure GPI4 to control watchdog timer functions or the programmable outputs.
18
GPI3
General-Purpose Logic Input 3. An internal 10A current source pulls GPI3 to GND.
Configure GPI3 to control watchdog timer functions or the programmable outputs.
19
GPI2
General-Purpose Logic Input 2. An internal 10A current source pulls GPI2 to GND.
Configure GPI2 to control watchdog timer functions or the programmable outputs.
20
GPI1
General-Purpose Logic Input 1. An internal 10A current source pulls GPI1 to GND.
Configure GPI1 to control watchdog timer functions or the programmable outputs.
21
ABP
Internal Power-Supply Output. Bypass ABP to GND with a 1F ceramic capacitor. ABP
powers the internal circuitry of the MAX6872/MAX6873. ABP supplies the input voltage to
the internal charge pumps when the programmable outputs are configured as charge-
pump outputs. Do not use ABP to supply power to external circuitry.
22
DBP
Internal Digital Power-Supply Output. Bypass DBP to GND with a 1F ceramic capacitor.
DBP supplies power to the EEPROM memory and the internal logic circuitry. Do not use
DBP to supply power to external circuitry.

IN6
Voltage Input 6. Configure IN6 to detect voltage thresholds between 1V and 5.5V in 20mV
increments, or 0.5V to 3.05V in 10mV increments. For improved noise immunity, bypass
IN6 to GND with a 0.1F capacitor installed as close to the device as possible.

IN5
Voltage Input 5. Configure IN5 to detect voltage thresholds between 1V and 5.5V in 20mV
increments, or 0.5V to 3.05V in 10mV increments. For improved noise immunity, bypass
IN5 to GND with a 0.1F capacitor installed as close to the device as possible.
27
IN4
Voltage Input 4. Configure IN4 to detect voltage thresholds between 1V and 5.5V in 20mV
increments, or 0.5V to 3.05V in 10mV increments. For improved noise immunity, bypass
IN4 to GND with a 0.1F capacitor installed as close to the device as possible.
28
IN3
Voltage Input 3. Configure IN3 to detect voltage thresholds between 1V and 5.5V in 20mV
increments, or 0.5V to 3.05V in 10mV increments. For improved noise immunity, bypass
IN3 to GND with a 0.1F capacitor installed as close to the device as possible.
29
IN2
Bipolar Voltage Input 2. Configure IN2 to detect negative voltage thresholds from -2.5V to
-15.25V in 50mV increments or -1.25V to -7.625V in 25mV increments. Alternatively,
configure IN2 to detect positive voltage thresholds from 2.5V to 15.25V in 50mV
increments or 1.25V to 7.625V in 25mV increments. For improved noise immunity, bypass
IN2 to GND with a 0.1F capacitor installed as close to the device as possible.
30
IN1
High-Voltage Input 1. Configure IN1 to detect voltage thresholds from 2.5V to 13.2V in
50mV increments or 1.25V to 7.625V in 25mV increments. For improved noise immunity,
bypass IN1 to GND with a 0.1F capacitor installed as close to the device as possible.
31
I.C.
Internal Connection. Leave unconnected.
32
2
PO1
Programmable Output 1. Configurable active-high, active-low, open-drain, weak pullup, or
charge-pump output. PO1 pulls low with a weak 10A internal current sink for 1V < VABP <
VUVLO. PO1 assumes its programmed conditional output state when ABP exceeds UVLO.

EP
Exposed Paddle. Exposed paddle is internally connected to GND.
