MAX16132–MAX16135
Low-Voltage, Precision, Single/Dual/Triple/
Quad-Voltage μP Supervisors
General Description
Benefits and Features
● High Precision
The MAX16132–MAX16135 are low-voltage, ±1% accurate,
single, dual, triple, and quad-voltage μP supervisors that
monitor up to 4 system-supply voltages for undervoltage
and overvoltage faults. The MAX16132–MAX16134 feature
independent reset outputs, while the MAX16135 features
dual reset outputs. For the MAX16132–MAX16134, a
reset output asserts when the voltage at its corresponding
input falls outside a factory-trimmed undervoltage and
overvoltage window threshold. The reset is maintained
for a minimum timeout period after voltage at the input
falls within the factory-set window threshold. For the
MAX16135, a reset output asserts when either, or both, of
the corresponding inputs fall outside the factory-trimmed
undervoltage and overvoltage window thresholds. See
Selector Guide for available options. These integrated
supervisory circuits significantly improve system reliability
and reduce size compared to separate ICs or discrete
components.
• ±1% Threshold Accuracy Over Temperature
● Programmable OV Threshold: 104% to 111%
● Programmable UV Threshold: 89% to 96%
● Programmable Input Voltage from 0.5V to 5.0V
● Low 15µA Supply Current
● Quad-Input Monitor
● 23 Programmable Reset Timeout Periods
● Immune to Short Monitored Supply Transients
● Guaranteed Correct Logic State Down to V
● Open-Drain Outputs
= 1V
DD
● Small SOT-23 Package
● -40°C to +125°C Automotive Operating Temperature
Range
The MAX16132–MAX16135 are fixed-threshold devices.
The nominal input voltage for any input is factory
programmable from 0.5 to 5.0V, providing a wide range
of threshold selections. The window threshold levels are
factory programmable from ±4% to ±11%, with ±1%
resolution and 0.25% or 0.50% hysteresis. The ±1%
threshold accuracy over temperature and window threshold
monitoring make these devices ideal for automotive
ADAS applications.
Ordering Information appears at end of data sheet.
The reset outputs are active-low, open-drain, and are
guaranteed to be in the correct reset output logic state
when V
remains greater than 1.0V. All devices are
DD
offered with 23 reset timeout periods ranging from 20µs
(min) to 1200ms (min). All reset outputs share the same
factory-set reset timeout period.
The MAX16132–MAX16135 are available in a small 8-pin
SOT23 package and specified over the automotive
temperature range of -40°C to +125°C.
Applications
● ADAS
● Multivoltage ASICs
● Storage Equipment
● Servers

The MAX16132–MAX16135 are immune to short IN_
transients. Each of the internal comparators are factory
set to either 0.5% or 0.25% hysteresis with respect to the
selected nominal input voltage. Hysteresis provides input
immunity to ambient noise without significantly reduc-
ing the input threshold accuracy. See the Maximum IN_
Transient Duration vs. Reset Threshold Overdrive graph
in the Typical Operating Characteristics section .
Detailed Description
Detailed Description
The MAX16132–MAX16135 are single, dual, triple, and
quad-voltage μP supervisors designed to maintain system
integrity in multi-supply systems. These devices offer
undervoltage and overvoltage window threshold monitoring
within ±1% accuracy over temperature.
Input Voltage
Reset Outputs
The MAX16132–MAX16135 feature factory-programmable
input-voltage-level options from 0.5V to 5V. See Table 1
thru Table 4, as well as the Selector Guide for standard
voltage options. The selection of nominal input voltage does
not set the voltage threshold levels. For the MAX16132–
MAX16135, the undervoltage and overvoltage thresholds
are determined by the selection of input tolerance.See
the Electrical Characteristics table and Input Tolerance/
Hysteresis section for more detail.
The MAX16132–MAX16134 feature independent, active-
low, open-drain reset outputs, while the MAX16135 features
dual reset outputs. For the MAX16132–MAX16134, when
an input voltage falls outside the set window threshold,
the corresponding reset outputs asserts. The reset output
de-asserts after the reset timeout period when the input
voltage falls within the window threshold. See Figure 1 for
more detail.
The MAX16135 feature dual reset outputs. RESET1
asserts when V
and/or V
falls outside the set

IN3
The MAX16132–MAX1635 are designed to offer eight
factory-programmable input tolerance levels from ±4% to
±11% in ±1% increments. The input tolerance level sets
the undervotlage and overvoltage threshold levels with
respect to the selected nominal input voltage. See Table
5 thru Table 8 for hysteresis and tolerance values.
V
falls outside the set window threshold. RESET1 and
IN4
RESET2 de-assert after the reset timeout period when
their corresponding input voltages are within the set win-
dow threshold. At power-up, resets stay asserted for the
reset timeout period once V
is above the UVLO. All
DD
reset outputs require a pullup resistor to V
.

The MAX16132–MAX16135 reset devices that monitor

selection. Tolerance setting determines the boundary for
undervoltage and overvoltage thresholds. The selected
nominal input voltage must stay within the window threshold
for the MAX16132–MAX16135 not to issue a reset signal.
See below for threshold calculation for 2.5V nominal input
voltage and ±10% input tolerance:
