Product Summary

The MAX813LESA+ 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. The MAX813LESA+ is the same as the MAX705, except RESET is provided instead of RESET. Two supply-voltage monitor levels are available: The MAX813LESA+ generate a reset pulse when the supply voltage drops below 4.65V, while the MAX706/MAX708 generate a reset pulse below 4.40V. MAX813LESA+ is available in 8-pin DIP, SO and μMAX packages.
