The MAX6412–MAX6420 low-power microprocessor
supervisor circuits monitor system voltages from 1.6V to
5V. These devices are designed to assert a reset signal
whenever the V
its reset threshold or the manual reset input is asserted.
The reset output remains asserted for the reset timeout
period after V
threshold and the manual reset input is deasserted. The
reset timeout is externally set by a capacitor to provide
more flexibility.
The MAX6412/MAX6413/MAX6414 feature fixed thresholds
from 1.575V to 5V in approximately 100mV increments and
a manual reset input. The MAX6415/MAX6416/MAX6417
are offered with an adjustable reset input that can monitor
voltages down to 1.26V and the MAX6418/MAX6419/
MAX6420 are offered with one fixed input and one
adjustable input to monitor dual-voltage systems.
The MAX6412/MAX6415/MAX6418 have an active-low,
push-pull reset output. The MAX6413/MAX6416/
MAX6419 have an active-high, push-pull reset output
and the MAX6414/MAX6417/MAX6420 have an active-
low, open-drain reset output. All of these devices are
offered in a SOT23-5 package and are fully specified
from -40°C to +125°C.

Note: The MAX6412/MAX6413/MAX6414 and MAX6418/
MAX6419/MAX6420 are available with factory-set V
thresholds from 1.575V to 5.0V in approximately 0.1V incre-
ments. Insert the desired nominal reset threshold suffix (from
Table 1) into the blanks following the letters UK. There are 33
standard versions with a required order increment of 2500
pieces. Sample stock is generally held on standard versions
only (see Standard Versions Table). Required order increment is
10,000 pieces for nonstandard versions. Contact factory for
availability. All devices are available in tape-and-reel only.
Devices are available in both leaded and lead-free packaging.
Specify lead-free by replacing “-T” with “+T” when ordering.
/V denotes an automotive qualified part.
