Product Summary

The MAX823MEUK+ is a 5-Pin microprocessor supervisory circuit. The MAX823MEUK+ combines reset output, watchdog, and manual-reset input functions in a 5-pin SOT23-5 package. The device significantly improves system reliability and accuracy compared to separate ICs or discrete components. The MAX823MEUK+ is specifically designed to ignore fast transients on VCC. Five preprogrammed reset threshold voltages are available, designated by the following package suffixes: L = 4.63V, M = 4.38V, T = 3.08V, S = 2.93V, and R = 2.63V. The applications of the MAX823MEUK+ include Battery-Powered Computers and Controllers, Embedded Controllers, Intelligent Instruments, Automotive Systems, Critical μP Monitoring, Portable/Battery-Powered Equipment.
