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.
