Product Summary

The MAX823SEUK is a microprocessor supervisory circuit. It combines reset output, watchdog, and manual reset input functions in 5-pin SOT23 and SC70 packages. The MAX823SEUK significantly improves system reliability and accuracy compared to separate ICs or discrete components. The MAX823SEUK is specifically designed to ignore fast transients on VCC. The applications of the MAX823SEUK+T include Computers and Controllers, Embedded Controllers, Intelligent Instruments, Automotive Systems, Critical µP Monitoring and Portable/Battery-Powered Equipment.
