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.

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.
