MAX6412–MAX6420 Low-Power, Single/Dual-Voltage μP Reset Circuits
with Capacitor-Adjustable Reset Timeout Delay General Description 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 VCC supply voltage or RESET IN falls
below its reset threshold or the manual reset input is
asserted. The reset output remains asserted for the reset
timeout period after VCC and RESET IN rise above the
reset 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 activelow, 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 -40В°C …
