Product Summary

The MAX6823SUK+T is a low-voltage microprocessor (μP) supervisory circuit that combine voltage monitoring, watchdog timer, and manual reset input functions in a 5-pin SOT23 package. Microprocessor supervisory circuits significantly improve system reliability and accuracy compared to separate ICs or discrete components. The device asserts a reset signal whenever the monitored voltage drops below its preset threshold, keeping it asserted for a minimum timeout period after VCC rises above the threshold. The applications of the MAX6823SUK+T include Set-Top Boxes, Computers and Controllers, Embedded Controllers, Intelligent Instruments, Automotive Systems, Critical μP Monitoring, Portable/Battery-Powered Equipment.
