The MAX700/MAX701/MAX702 are supervisory circuits
used to monitor the power supplies in microprocessor
(µP) and digital systems. The active-low RESET/RESET outputs of
the MAX700/MAX701/MAX702 are guaranteed to be in
the correct state for VCC voltages down to +1V (Figure 4).
They provide excellent circuit reliability and low cost by
eliminating external components and adjustments when
used with +5V-powered circuits.
The MAX702 is the simplest part in the family. When
VCC falls to 4.65V, active-low RESET goes low. The MAX702 also
provides a debounced manual reset input. The
MAX701 performs the same functions but has both
active-low RESET and RESET outputs. Their primary function is to
provide a system reset. Accordingly, an active reset
signal is supplied for low supply voltages and for at
least 200ms after the supply voltage reaches its operating
value.
In addition to the features of the MAX701 and MAX702,
the MAX700 provides preset or adjustable voltage
detection so thresholds other than 4.65V can be selected,
and adjustable hysteresis. All parts are supplied in
8-pin PDIP and Narrow SO packages in commercial
and extended temperature ranges.
