Product Summary
The MAX709LCSA+T is a power-supply monitor. When VCC falls below the reset threshold, RESET goes low and holds the μP in reset for 140ms min after VCC rises above the threshold. The RESET output is guaranteed to be in the correct state with VCC down to 1V. The MAX709LCSA+T provides excellent circuit reliability and low cost by eliminating external components and adjustments when used with +5V, +3.3V, or +3V powered systems. The MAX709LCSA+T is available 8-pin DIP, μMAX, and SO packages.
