to a 5.5V to 72V supply.
Ground
Active-Low Enable Input. Drive
EN
low to turn on the voltage detectors. Drive
EN
high to force the

Open-Drain Monitor B Output. Connect a pullup resistor from OUTB to V

INB- exceeds V
TH+
and goes high when INB- drops below V
TH-
(with LOGIC connected to GND
OUTB for the MAX16011). Drive LOGIC high to reverse OUTB’s logic state. OUTB is usually used as an
overvoltage output. OUTB goes low (LOGIC = low) or high (LOGIC = high) when V
CC
drops below
the UVLO threshold voltage.
INB-
Adjustable Voltage Monitor Threshold Input
Active-High ENABLE Input. For the MAX16010/MAX16011, drive EN high to turn on the voltage
detectors. Drive EN low to force OUTA low and OUTB low (LOGIC = low) or high (LOGIC = high). For
the MAX16013/MAX16014, drive EN high to enhance the p-channel MOSFET (P2), and drive EN low
to turn off the MOSFET. EN is internally pulled down to GND. Connect EN to V
CC
if not used.

OUTA INA+ drops below V

Open-Drain Comparator Output. Connect a pullup resistor from OUT to V
CC
. OUT goes low when
IN+ drops below IN-. OUT goes high when IN+ exceeds IN-.
Inverting Comparator Input
Internal 1.30V Reference Output. Connect REF to IN+ for active-low output. Connect REF to IN- for
active-high output. REF can source and sink up to 1µA. Leave REF floating if not used. REF output
is stable with capacitive loads from 0 to 50pF.

Gate-Driver Output. Connect GATE2 to the gate of an external p-channel MOSFET pass switch.
GATE2 is driven low to the higher of V
CC
- 10V or GND during normal operations and quickly
GATE2 shorted to V
CC
during an overvoltage condition (SET above the internal threshold). GATE2 is
shorted to V
