General Description
The MAX6874/MAX6875 EEPROM-configurable, multi-
voltage supply sequencers/supervisors monitor several
voltage detector inputs and general-purpose logic
inputs, and provide programmable open-drain outputs
for highly configurable power-supply sequencing appli-
cations. The MAX6874 provides six voltage monitor
inputs, four general-purpose inputs, and eight program-
mable open-drain outputs. The MAX6875 provides four
voltage monitor inputs, three general-purpose inputs,
and five programmable open-drain outputs. Manual reset
and margin disable inputs provide additional flexibility.
All voltage detectors offer configurable thresholds for
undervoltage detection. One high-voltage input (IN1)
provides detector threshold voltages from +2.5V to
+13.2V in 50mV increments, or from +1.25V to +7.625V
in 25mV increments. A second positive input (IN2) pro-
vides detector threshold voltages from +2.5V to +5.5V
in 50mV increments, or from +1.25V to +3.05V in 25mV
increments. Positive inputs (IN3–IN6) provide detector
threshold voltages from +1V to +5.5V in 20mV incre-
ments, or from +0.5V to +3.05V in 10mV increments.
Programmable output stages control power-supply
sequencing or system resets/interrupts. Program the
open-drain outputs as active-high or active-low.
Programmable timing delay blocks configure each output
to wait between 25μs and 1600ms before deasserting.
An SMBus?/I 2 C-compatible serial data interface pro-
grams and communicates with the configuration EEP-
ROM, the configuration registers, and the internal 4kb
