μP Reset Circuits
General Description
The MAX6326/MAX6327/MAX6328/MAX6346/MAX6347/
MAX6348 microprocessor (μP) supervisory circuits moni-
tor the power supplies in μP and digital systems. These
devices provide excellent circuit reliability and low cost
by eliminating external components and adjustments
when used with 2.5V, 3V, 3.3V, and 5V powered circuits.
These circuits perform a single function: they assert a
reset signal whenever the V CC supply voltage declines
below a preset threshold, keeping it asserted for at least
100ms after V CC has risen above the reset threshold.
The only difference between the devices is their output.
The MAX6326/MAX6346 (push-pull) and MAX6328/
MAX6348 (open-drain) have an active-low reset output.
The MAX6327/MAX6347 have an active-high push-pull
reset output. All of these parts are guaranteed to be in
the correct state for V CC down to 1V. The reset compara-
tor is designed to ignore fast transients on V CC . Reset
thresholds are factory-trimmable between 2.2V and
4.63V, in approximately 100mV increments. Twenty-one
standard versions are available. Contact the factory for

Ordering Information
availability of nonstandard versions.
Ultra-low supply currents (1μA max for the MAX6326/
MAX6327/MAX6328) make these parts ideal for use in
portable equipment. All six devices are available in
space-saving SOT23 and SC70 packages.
