Ultra-Small, Overvoltage Protection/Detection Circuits
General DescriptionThe 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.

Pin Description
Detailed DescriptionThe 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 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 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-
protection circuits 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 voltage drop.
While 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.
Voltage MonitoringThe MAX16010/MAX16011 include undervoltage and over-
voltage comparators for window detection (see Figure
1). OUT_ asserts high when the monitored voltage is
within the selected “window.” OUTA asserts low when the
monitored voltage falls below the lower (VTRIPLOW) limit of
the window, or OUTB asserts low if the monitored voltage
exceeds the upper limit (VTRIPHIGH). The application in
Figure 1 shows OUT_ enabling the DC-DC converter when
the monitored voltage is in the selected window.
The resistor values (R1–R3) can be calculated as follows:
TOTALTRIPLOWTHV V R2 R3−=+
TOTALTRIPHIGHTHV V R3+=
where RTOTAL = R1 + R2 + R3.
Use the following steps to determine the values for
R1–R3.
1) Choose a value for RTOTAL, the sum of R1, R2, and
R3. Because the MAX16010/MAX16011 have very
high input impedance, RTOTAL can be up to 5MΩ.
2) Calculate R3 based on RTOTAL and the desired upper
trip point:TOTAL
TRIPHIGH RR3 V+×=
3) Calculate R2 based on RTOTAL, R3, and the desired
lower trip point:TOTAL
TRIPHIGH RR3 V+×=
4) Calculate R1 based on RTOTAL, R3, and R2:
R1 = RTOTAL - R2 - R3
The MAX16012 has both inputs of the comparator avail-
able with an integrated 1.30V reference (REF). When
the voltage at IN+ is greater than the voltage at IN-, OUT
goes high. When the voltage at IN- is greater than the
voltage at IN+, OUT goes low. Connect REF to IN+ or
IN- to set the reference-voltage value. Use an external
resistive divider to set the monitored voltage threshold.
