General Description
The MAX705-MAX708/MAX813L microprocessor (µP)supervisory circuits reduce the complexity and numberof components required to monitor power-supply andbattery functions in µP systems. These devices signifi-cantly improve system reliability and accuracy com-pared to separate ICs or discrete components.The MAX705/MAX706/MAX813L provide four functions:1) A reset output during power-up, power-down, andbrownout conditions.2) An independent watchdog output that goes low ifthe watchdog input has not been toggled within 1.6seconds.3) A 1.25V threshold detector for power-fail warning,low-battery detection, or for monitoring a power sup-ply other than +5V.4) An active-low manual-reset input.The MAX707/MAX708 are the same as the MAX705/MAX706, except an active-high reset is substituted forthe watchdog timer. The MAX813L is the same as theMAX705, except RESET is provided instead of RESET.Two supply-voltage monitor levels are available: TheMAX705/MAX707/MAX813L generate a reset pulse whenthe supply voltage drops below 4.65V, while theMAX706/MAX708 generate a reset pulse below 4.40V.All four parts are available in 8-pin DIP, SO and µMAXpackages
