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 automotive,
telecom, and industrial applications. These devices oper-
ate 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
overvoltage 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 inde-
pendent reference output. The reference output can be
directly connected to either the inverting or noninverting
input to select the comparator output logic.
The MAX16013 and MAX16014 are overvoltage protec-
tion circuits that are capable of driving two p-channel
MOSFETs to prevent reverse-battery and overvoltage
www.DataSheet4U.comconditions. One MOSFET (P1) eliminates the need for
external diodes, thus minimizing the input voltage drop.
The second MOSFET (P2) isolates the load or regulates
the output voltage during an overvoltage condition. 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/MAX16013/
MAX16014 are available in small 6-pin TDFN packages.
These devices are fully specified from -40°C to +125°C.
