Maxim MAX708ESA

简单复位/加电复位4.4V1

Overview

The MAX705–MAX708/MAX813L microprocessor (μP) supervisory circuits reduce the complexity and number of components required to monitor power-supply and battery functions in μP systems. These devices significantly improve system reliability and accuracy compared to separate ICs or discrete components.

Two supply-voltage monitor levels are available: The MAX705/MAX707/MAX813L generate a reset pulse when the supply voltage drops below 4.65V, while the MAX706/MAX708ESA generate a reset pulse below 4.40V. All four parts are available in 8-pin DIP, SO and μMAX packages.
