Description

General part information

MAX824 Series

The MAX823/MAX824/MAX825 microprocessor (µP) supervisory circuits combine reset output, watchdog, and manual reset input functions in 5-pin SOT23 and SC70 packages. They significantly improve system reliability and accuracy compared to separate ICs or discrete components. The MAX823/MAX824/MAX825 are specifically designed to ignore fast transients on VCC.Seven preprogrammed reset threshold voltages are available (seeReset Threshold Tablein the full data sheet). All three devices have an active-low reset output, which is guaranteed to be in the correct state for VCCdown to 1V. The MAX823 also offers a watchdog input and manual reset input. The MAX824 offers a watchdog input and a complementary active-high reset. The MAX825 offers a manual reset input and a complementary active-high reset. The Selector Guide explains the functions offered in this series of parts.ApplicationsAutomotive ElectronicsComputers and ControllersCritical µP MonitoringEmbedded ControllersIntelligent InstrumentsPortable Battery-Powered Equipment
