MR
Manual Reset Input.
MR is configurable to either assert PO_ into a programmed
state or to have no effect on PO_ when driving
MR low (see Table 6). Leave MR
unconnected or connect to DBP if unused.
MR is internally pulled up to DBP
through a 10A current source.

SDA
Serial Data Input/Output (Open Drain). SDA requires an external pullup resistor.
14
12
9
SCL
Serial Clock Input. SCL requires an external pullup resistor.
15
13
10
A0
Address Input 0. Address inputs allow up to four (MAX6889/MAX6890) or two
(MAX6891) connections on one common bus. Connect A0 to GND or to the
serial-interface power supply.

A1
Address Input 1. Address inputs allow up to four MAX6889/MAX6890
connections on one common bus. Connect A1 to GND or to the serial-interface
power supply.

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
16
11
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
17
12
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
18
13
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

14
VCC
Internal Power-Supply Voltage. Bypass VCC to GND with a 1F ceramic
capacitor. VCC supplies power to the internal circuitry. VCC is internally powered
from the highest of the monitored IN1–IN5 voltages. Do not use VCC to supply
power to external circuitry. To externally supply VCC, see the Powering the
MAX6889/MAX6890/MAX6891 section.

15
DBP
Internal Digital Power-Supply Voltage. Bypass DBP to GND with a 1F ceramic
capacitor. DBP supplies power to the EEPROM memory, the internal logic
circuitry, and the programmable outputs. Do not use DBP to supply power to
external circuitry.
23

IN8
High-Voltage Input 8. Configure IN8 to detect 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 IN8 to GND with a 0.1F capacitor installed as
close to the device as possible.
24
—
IN7
Voltage Input 7. Configure IN7 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 IN7 to GND with a 0.1F capacitor installed as close to the
device as possible.
