Maxim MAX709MCPA

简单复位/加电复位4.4V1

Overview

The MAX709MCPA provides a system reset during power-up, power-down, and brownout conditions. 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 MAX709MCPA provides excellent circuit reliability and low cost by eliminating external components and adjustments when used with +5V, +3.3V, or +3V powered systems. The MAX709MCPA is available 8-pin DIP, μMAX, and SO packages.
