MAXIM MAX708SESA+T

The MAX706P/R/S/T and MAX708R/S/T microprocessor (μP) supervisory circuits reduce the complexity and number of components required to monitor +3V power-supply levels in +3V to +5V systems. These devices significantly improve system reliability and accuracy compared to separate ICs or discrete components.

• The MAX706P/R/S/T supervisory circuits provide the following four functions:
  • A reset output during power-up, power-down, and brownout conditions.
  • An independent watchdog output that goes low if the watchdog input has not been toggled within 1.6 sec.
  • A 1.25V threshold detector for power-fail warning, low battery detection, or for monitoring a power supply other than the main supply.
  • An active-low manual-reset input.
• The only difference between the MAX706R, MAX706S, and MAX706T is the reset-threshold voltage levels, which are 2.63V, 2.93V, and 3.08V, respectively. All have active low reset output signals. The MAX706P is identical to the MAX706R, except its reset output signal is active-high.
• The MAX708R/S/T provide the same functions as the MAX706R/S/T, except they do not have a watchdog timer. Instead, they provide both RESET and RESET outputs. As with the MAX706, devices with R, S, and T suffixes have reset thresholds of 2.63V, 2.93V and 3.08V, respectively.
• All seven devices are offered in 8-pin SO, DIP, and μMAX packages.
