MAX823SEUK Datasheet

5-Pin Microprocessor Supervisory Circuits With Watchdog Timer and Manual Reset


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 relia- bility and accuracy compared to separate ICs or discrete components. The MAX823/MAX824/MAX825 are specifi- cally designed to ignore fast transients on VCC.
