100 pcs. maxim# MAX6328XR29-t, ultra-low-power micropro
Ultra-low-power microprocessor supervisory circuit (reset output active-low, open-drain). Reset threshold (typ) 2.930V. Standard version
The MAX6326/MAX6327/MAX6328/MAX6346/MAX6347/
MAX6348 microprocessor ( P) supervisory circuits monitor
the power supplies in P 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
below a preset threshold, keeping it asserted for at least
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
CC down to 1V. The reset comparator
is designed to ignore fast transients on V
thresholds are factory-trimmable between 2.2V and
4.63V, in approximately 100mV increments. Twenty-one
standard versions are available. Contact the factory for
availability of nonstandard versions.
Ultra-low supply currents (1 A 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.
