NAME
FUNCTION
Manual Reset Input. MR is configurable to either assert PO_ into a programmed

MR
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 10μA current source.

Serial Data Input/Output (Open Drain). SDA requires an external pullup resistor.
Serial Clock Input. SCL requires an external pullup resistor.
Address Input 0. Address inputs allow up to four (MAX6889/MAX6890) or two

A0
(MAX6891) connections on one common bus. Connect A0 to GND or to the
serial-interface power supply.
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.
General-Purpose Logic Input 4. An internal 10μA current source pulls GPI4 to

GPI1
GND. Configure GPI1 to control watchdog timer functions or the programmable
outputs.
Internal Power-Supply Voltage. Bypass V CC to GND with a 1μF ceramic
capacitor. V CC supplies power to the internal circuitry. V CC is internally powered

from the highest of the monitored IN1–IN5 voltages. Do not use V CC to supply
power to external circuitry. To externally supply V CC , see the Powering the
MAX6889/MAX6890/MAX6891 section.
Internal Digital Power-Supply Voltage. Bypass DBP to GND with a 1μF ceramic

DBP
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.
High-Voltage Input 8. Configure IN8 to detect voltage thresholds from 2.5V to

IN8
15.25V in 50mV increments, or 1.25V to 7.625V in 25mV increments. For
improved noise immunity, bypass IN8 to GND with a 0.1μF capacitor installed as
close to the device as possible.
Voltage Input 7. Configure IN7 to detect voltage thresholds between 1V and 5.5V

IN7
in 20mV increments, or 0.5V to 3.05V in 10mV increments. For improved noise
immunity, bypass IN7 to GND with a 0.1μF capacitor installed as close to the
device as possible.
