MAX16010–MAX16014
Ultra-Small, Overvoltage Protection/
Detection Circuits
General Description
The MAX16010–MAX16014 is a family of ultra-small, low-
power, overvoltage-protection circuits for high-voltage,
high-transient systems such as those found in telecom
and industrial applications. These devices operate over
a wide 5.5V to 72V supply voltage range, making them
also suitable for other applications such as battery stacks,
notebook computers, and servers.
The MAX16010 and MAX16011 offer two independent
comparators for monitoring both undervoltage and over-
voltage conditions. These comparators offer open-drain
outputs capable of handling voltages up to 72V. The
MAX16010 features complementary enable inputs (EN/
EN), while the MAX16011 features an active-high enable
input and a selectable active-high/low OUTB output.
The MAX16012 offers a single comparator and an
independent reference output. The reference output can
be directly connected to either the inverting or noninvert-
ing input to select the comparator output logic.
The MAX16013 and MAX16014 are overvoltage-
protection circuits that are capable of driving two
p-channel MOSFETs to prevent reverse-battery and
overvoltage conditions. One MOSFET (P1) eliminates the
need for external diodes, thus minimizing the input volt-
age drop. The second MOSFET (P2) isolates the load or
regulates the output voltage during an overvoltage condi-
tion. The MAX16014 keeps the MOSFET (P2) latched off
until the input power is cycled.
The MAX16010 and MAX16011 are available in small
8-pin TDFN packages, while the MAX16012–MAX16014
are available in small 6-pin TDFN packages. These
devices are fully specified from -40°C to +125°C.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these
or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect
device reliability.
