Product Summary

The MAX809J is a microprocessor supervisory circuit used to monitor the power supplies in μP and digital systems. The device provides excellent circuit reliability and low cost by eliminating external components and adjustments when used with +5V, +3.3V, +3.0V, or +2.5V-powered circuits. The applications of the MAX809J include Computers, Controllers, Intelligent Instruments, Critical μP and μC Power Monitoring, Portable/Battery-Powered Equipment and Automotive.
