MAX824 Datasheet (Maxim) - 5-Pin Microprocessor Supervisory Circuits

MAX824, 5-Pin Microprocessor Supervisory Circuits

The MAX823/MAX824/MAX825 * microprocessor (µP) supervisory circuits combine reset output, watchdog, and manual-reset input functions in a 5-pin SOT23-5 package.

They significantly improve system reliability and accuracy compared to separate ICs or discrete components.

The MAX823/MAX824/MAX825 are
