Product Summary

The max709lcsa is a Power-Supply Monitor with Reset. The max709lcsa 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 uP in reset for 140ms min after VCC rises above the threshold. The applications of the max709lcsa are Minimum Component Count, Low-Cost Processor Systems.
