监控电路 5-Pin MPU Supervisor

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

MAX823REUK+T General Description 

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.
