MAX16132–MAX16135
Low-Voltage, Precision, Single/Dual/Triple/
Quad-Voltage μP Supervisors
General Description
Benefits and Features
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 the Selector Guide for available options. These
integrated supervisory circuits significantly improve system reliability and reduce size compared to separate ICs
or discrete components.
● High Precision
• ±1% Threshold Accuracy over Temperature
The MAX16132–MAX16135 are fixed-threshold devices.
The nominal input voltage for any input is factory-programmable from 1.0V to 5.0V, providing a wide range of threshold selections. The window threshold levels are factoryprogrammable 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.
The reset outputs are active-low, open-drain, and are
guaranteed to be in the correct reset output logic state
when VDD remains greater than 1.07V. All devices are
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.

MAX16132–MAX16135
Low-Voltage, Precision, Single/Dual/Triple/QuadVoltage μP Supervisors
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
The MAX16132–MAX16135 feature factory-programmable input-voltage-level options from 1.0V 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.
Input Tolerance/Hysteresis
The MAX16132–MAX1635 are designed to offer eight factory-programmable input tolerance levels from ±4% to ±11%
in ±1% increment. The input tolerance level sets the undervoltage and overvoltage threshold levels with respect to the
selected nominal input voltage. See Table 5 thru Table 8 for hysteresis and tolerance values.
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 reducing the input threshold accuracy. See the Maximum IN_ Transient Duration vs.
Reset Threshold Overdrive graph in the Typical Operating Characteristics section.
Reset Outputs
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 deasserts after the reset timeout period when the input voltage
falls within the window threshold. See Figure 1 below for more detail.
The MAX16135 feature dual reset outputs. RESET1 asserts when VIN1 and/or VIN2 falls outside the set window
threshold. RESET2 asserts when VIN3 and/or VIN4 falls outside the set window threshold. RESET1 and RESET2 deassert after the reset timeout period when their corresponding input voltages are within the set window threshold. At
power-up, resets stay asserted for the reset timeout period once VDD is above the UVLO. All reset outputs require a
pullup resistor to VDD.

MAX16132–MAX16135
Low-Voltage, Precision, Single/Dual/Triple/QuadVoltage μP Supervisors
Applications Information
Unused Inputs
The MAX16132–MAX16135 are capable of monitoring inputs for undervoltage and overvoltage events within a very
narrow voltage window. Connect any unused IN_ input to its nominal voltage setting.
Setting Input Thresholds
The MAX16132–MAX16135 reset devices that monitor input within a window threshold set by the input tolerance
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:
VINNOM = 2.5V
TOL = ± 10 %
VUVTH = VINNOM(1 − 10 % ) = 2.5V(1 − 0.1) = 2.5V − 0.250V = 2.250V
VOVTH = VINNOM(1 + 10 % ) = 2.5V(1 + 0.1) = 2.5V + 0.250V = 2.750V
Where VINNOM is the selected nominal input voltage, TOL is the input tolerance, VUVTH is undervoltage threshold
voltage and VOVTH is the overvoltage threshold voltage.
The MAX16132–MAX16135 feature ±1% threshold accuracy over temperature. This excursion must be added to the
calculated undervoltage and overvoltage threshold settings to account for the threshold variation as shown below:
VUVTH_EXC = VUVTH(1 ± 1 % ) = 2.250V(1 ± 0.01) = 2.250V ± 0.0225V
VOVTH_EXC = VOVTH(1 ± 1 % ) = 2.750V(1 ± 0.01) = 2.750V ± 0.0275V
Where VUVTH_EXC is the undervoltage threshold variation and VOVTH_EXC is the overvoltage threshold variation.
Undervoltage/Overvoltage-Detection Circuit
The open-drain outputs of the MAX16132–MAX16135 can be configured to detect an undervoltage/overvoltage condition.
Figure 2 shows the MAX16132 reset output deriving an LED when there is an overvoltage/undervoltage event on IN.
Note: The value for the current-limiting resistor R must be chosen such that it does not violate the absolute maximum
ratings of the reset pin.

Power-Supply Bypassing and Grounding
The MAX16132–MAX16135 operate from a 1.71V to 5.5V supply. An undervoltage lockout ensures that the outputs are
in the correct states when the UVLO is exceeded. Bypass VDD to ground with a 0.1μF capacitor as close to the device
as possible. Additional capacitor improves transient immunity. For fast transients with large voltage excursion, a filter
resistor in series with the bypass capacitor is recommended for proper device operation. See Figure 3 below for more
detail.
