General Description
The MAX6351–MAX6360 microprocessor (P) supervi-
sors with multiple reset voltages significantly improve
system reliability and accuracy compared to separate
ICs or discrete components. If any input supply voltage
drops below its associated preset threshold, all reset
outputs are asserted. In addition, the output(s) is valid
as long as either input supply voltage remains greater
than +1.0V.
All devices in this series have an active-low debounced
manual reset input. In addition, the MAX6358/MAX6359/
MAX6360 offer a watchdog timer input with a 46.4sec
start-up timeout period and a 2.9sec timeout period.
The MAX6355/MAX6356/MAX6357 offer an additional
voltage monitor input to monitor a third voltage.
The MAX6351 features both 3V and 5V active-low push-
pull reset outputs. The MAX6353/MAX6356/MAX6359
offer a 5V active-low push-pull reset. The MAX6354/
MAX6357/MAX6360 offer a 3V active-low push-pull
reset. The MAX6352/MAX6355/MAX6358’s reset is
active-low open-drain.
All of these devices are offered with a wide variety of
voltage threshold levels, as shown in the
Voltage
Threshold Levels table below. They are available in 5-
and 6-pin SOT23 packages and operate over the
extended (-40°C to +85°C) temperature range.
