NAME
FUNCTION
MAX6457: Open-Drain Monitor Output. OUT requires an external pullup
resistor. OUT asserts low for V CC between 1.5V and 4V. OUT asserts low
when V IN+ drops below V TH- and goes high after the timeout period (t TP )
when V IN+ exceeds V TH+ .
MAX6458: Open-Drain Monitor Output. OUT requires an external pullup

OUT
resistor. OUT asserts low for V CC between 1.5V and 4V. OUT asserts low
when V IN+ drops below V TH- or when V IN- exceeds V TH+ . OUT goes
high after the timeout period (t TP ) when V IN+ exceeds V TH+ and V IN-
drops below V TH- .
MAX6460: Open-Drain Monitor Output. OUT requires an external pullup
resistor. OUT asserts low for V CC between 1.5V and 4V. OUT asserts low
when V IN+ drops below V IN- . OUT goes high when V IN+ is above V IN- .
Open-Drain Monitor A Undervoltage Output. OUTA requires an external

OUTA
pullup resistor. OUTA goes low when V IN+ drops below V TH- and goes
high when V IN+ exceeds V TH+ . OUTA also goes low for V CC between
1.5V and 4V.
Open-Drain Monitor B Overvoltage Output. OUTB requires an external

OUTB
pullup resistor. OUTB goes low when V IN- exceeds V TH+ and goes high
when V IN- drops below V TH- . OUTB also goes low when V CC drops
below 4V.

CLEAR
Connect CLEAR to GND to make the latch transparent. CLEAR must be
low when powering up the device. Connect CLEAR to GND when not
used.
Reference. Internal 2.25V reference output. Connect REF to IN+ through
a voltage divider for active-low output. Connect REF to IN- through a

REF
voltage divider for active-high output. REF can source up to 100μA and
sink up to 300nA. Leave REF floating when not used. REF output is
stable with capacitive loads from 0 to 50pF or greater than 1μF.
