Detailed 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 automo-
tive, 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
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

where R TOTAL = R1 + R2 + R3.
Use the following steps to determine the values for R1,
R2, and R3.
1) Choose a value for R TOTAL , the sum of R1, R2, and
R3. Because the MAX16010/MAX16011 have very
high input impedance, R TOTAL can be up to 5M ? .
2) Calculate R3 based on R TOTAL and the desired
upper trip point:
R 3 =
V TRIPHIGH
3) Calculate R2 based on R TOTAL , R3, and the desired
lower trip point:
output.
The MAX16012 offers a single comparator and an inde-
pendent reference output. The reference output can be
R 2 =
V TH ? × R TOTAL
V TRIPLOW
? R 3
directly connected to either the inverting or noninvert-
ing 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
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 reg-
ulates the output voltage during an overvoltage condi-
tion. The MAX16014 keeps the MOSFET (P2) latched
off until the input power is cycled.
4) Calculate R1 based on R TOTAL , R3, and R2:
R1 = R TOTAL - 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- then OUT
goes high. When the voltage at IN- is greater than the
voltage at IN+ then 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.
