Processor Supervisor 2.63V 2.5V/3V/3.3V/5V 5-Pin SC-70 T/R

The MAX824 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 MAX824 is a specifically designed to ignore fast transients on VCC. Seven preprogrammed reset threshold voltages are available . All three devices have an active-low reset output, which is guaranteed to be in the correct state for VCC down to 1V. The MAX824 also offers a watchdog input and manual reset input. The MAX824 offers a watchdog input and a complementary active-high reset. The MAX824 offers a manual reset input and a complementary active-high reset. The Selector Guide explains the functions offered in this series of parts.
