MAX6700/MAX6710
Low-Voltage, High-Accuracy, Triple/Quad
Voltage μP Supervisory Circuits in SOT Package
General Description
The MAX6700/MAX6710 precision triple/quad voltage
microprocessor (μP) supervisory circuits monitor up to
four system-supply voltages and assert a single reset
if any supply voltage drops below its preset threshold.
These devices significantly reduce system size and
component count while improving reliability compared to
separate ICs or discrete components.
A variety of factory-trimmed threshold voltages are available
to accommodate different supply voltages and tolerances with
minimal external component requirements. The MAX6710
includes internally fixed options for monitoring 5.0V, 3.3V,
3.0V, 2.5V, and 1.8V supplies with -5% or -10% tolerances.
The MAX6710 is also available with one to three adjustable
threshold options to monitor voltages down to 0.62V. The
MAX6700 monitors three voltages with adjustable thresholds
down to 0.62V.
A single active-low output asserts when any monitored
input falls below its associated threshold. The open-drain
output has a weak internal pullup (10μA) to IN2. For the
MAX6710, reset remains low for the reset timeout period
(140ms min) after all voltages rise above the selected
threshold. The MAX6700 acts as a voltage detector with
a propagation delay of 5μs after all monitored voltages
exceed their thresholds. The output remains valid as
long as either IN2 or IN2 input voltage remains above 1V
(MAX6710) or VCC is above 2V (MAX6700/MAX6710Q).
The MAX6700/MAX6710 are available in a small 6-pin
SOT23 package and operate over the extended (-40°C to
+85°C) temperature range.
