EEPROM-Programmable, Hex/Quad,
Power-Supply Sequencers/Supervisors
when that output is logic-high. No output can depend
solely on MR .
The positive voltage monitors generate fault signals
(logical 0) to the MAX6872/MAX6873s’ logic array when
an input voltage is below the programmed undervolt-
age threshold, or when that voltage is above the over-
voltage threshold. The negative voltage monitor (IN2)
generates a fault signal to the logic array when the
input voltage is less negative than the undervoltage
threshold, or when that voltage is more negative than
the overvoltage threshold.
Registers 0Eh through 3Ah and 40h configure each of
the programmable outputs. Programmable timing
blocks set the PO_ timeout period from 25μs to 1600ms
