Power-Supply Monitor with Reset
General Description
The MAX700/MAX701/MAX702 are supervisory circuits
used to monitor the power supplies in microprocessor
(μP) and digital systems. The RESET /RESET outputs of
the MAX700/MAX701/MAX702 are guaranteed to be in
the correct state for V CC 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
V CC falls to 4.65V, RESET goes low. The MAX702 also
provides a debounced manual reset input. The
MAX701 performs the same functions but has both
RESET and RESET outputs. Their primary function is to
provide a system reset. Accordingly, an active reset
Features
? Min 200ms RESET Pulse on Power-Up, Power-
Down, and During Low-Voltage Conditions
? Reset Threshold Factory Trimmed for +5V
Systems
? No External Components or Adjustments with
+5V-Powered Circuits
? Debounced Manual Reset Input
? Preset or Adjustable Voltage Detection (MAX700)
? Adjustable Hysteresis (MAX700)
? 8-Pin PDIP and Narrow SO Packages
Ordering Information
signal is supplied for low supply voltages and for at
least 200ms after the supply voltage reaches its operat-
ing 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 select-
ed, and adjustable hysteresis. All parts are supplied in
8-pin PDIP and Narrow SO packages in commercial
and extended temperature ranges.
