Product Summary
The MAX825TEUK+T is a microprocessor supervisory circuit. The MAX825TEUK+T combines reset output, watchdog, and manual-reset input functions in a 5-pin SOT23-5 package. The MAX825TEUK+T significantly improves system reliability and accuracy compared to separate ICs or discrete components. The MAX825TEUK+T is specifically designed to ignore fast transients on VCC. The applications of the device include Battery-Powered Computers and Controllers, Embedded Controllers, Intelligent Instruments, Automotive Systems, Critical μP Monitoring and Portable/Battery-Powered Equipment.
