NAME
FUNCTION
77
MARGIN
Margin Input. MARGIN holds RESET, UV/OV, and WDO in their existing states when
MARGIN is driven low. Leave MARGIN unconnected or connect to DBP if unused.
MARGIN is internally pulled up to DBP through a 10A current source. MARGIN
overrides MR if both are asserted at the same time.
88
SDA
Serial Data Input/Output (Open Drain). SDA requires an external pullup resistor.
99
SCL
Serial-Interface Clock Input. SCL requires an external pullup resistor.
10
A0
Serial Address Input 0. Allows up to 2 devices to share a common bus. Connect A0 to
ground or the serial-interface power supply.
11
REFIN
Reference Voltage Input. Program the device for external or internal reference. Connect
an external +1.225V to +1.275V reference to REFIN when using an external reference.
Leave REFIN unconnected when using the internal reference.
12
AUXIN
Auxiliary Input. A 10-bit ADC converts the input voltage at AUXIN. The high-impedance
AUXIN input accepts input voltages up to 1.25V. AUXIN does not affect programmable
outputs.
11, 12
N.C.
No Connection. Not internally connected.
13
VCC
Internal Power-Supply Voltage. Bypass VCC to GND with a 1F ceramic capacitor as
close to the device as possible. VCC supplies power to the internal circuitry. VCC is
internally powered from the highest of the monitored IN1–IN4 voltages. Do not use VCC
to supply power to external circuitry. To externally supply VCC, see the Powering the
MAX6884/MAX6885 section.
14
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.
15
IN6
Voltage-Detector Input 6. Program two thresholds per voltage-detector input
(undervoltage UV and undervoltage/overvoltage UV/OV). Program IN6 detector
thresholds from 1V to 5.8V in 20mV increments, 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.
16
IN5
Voltage-Detector Input 5. Program two thresholds per voltage-detector input
(undervoltage UV and undervoltage/overvoltage UV/OV). Program IN5 detector
thresholds from 1V to 5.8V in 20mV increments, 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.
17
IN4
Voltage-Detector Input 4. Program two thresholds per voltage-detector input
(undervoltage UV and undervoltage/overvoltage UV/OV). Program IN4 detector
thresholds from 1V to 5.8V in 20mV increments, 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. Program the device to receive power through IN1–IN4 inputs
or VCC (see the Powering the MAX6884/MAX6885 section).
