Product Summary
The max811seus+t is a low-power microprocessor (μP) supervisory circuit used to monitor power supplies in μP and digital systems. The max811seus+t provides excellent circuit reliability and low cost by eliminating external components and adjustments when used with 5V- powered or 3V-powered circuits. The max811seus+t also provides a debounced manual reset input. Low supply current makes it ideal for use in portable equipment. The device comes in a 4-pin SOT143 package. Applications include: Computers, Controllers, Intelligent Instruments, Critical μP and μC Power Monitoring, Portable/Battery-Powered Equipment.
