The MAX813LEUA+ is a compact, highly integrated supervisory circuit designed by Maxim Integrated to monitor power supplies in microprocessor and digital systems. It provides a precise, low-power solution for system reset and voltage monitoring, ensuring reliable operation and protection against power failures or brownout conditions.

Key Features

• Voltage Monitoring: This device is capable of monitoring a +5V power supply, providing a quick response to any detected undervoltage condition.
• Power-On Reset: The MAX813LEUA+ generates a reset signal whenever the monitored supply voltage falls below the factory-set reset threshold, maintaining it active for a minimum of 140ms after the supply has risen above the reset threshold, ensuring a proper system reset.
• Manual Reset: An additional feature includes a manual reset input that allows for a system reset to be generated on demand.
• Low Power Consumption: Designed for power-sensitive applications, it operates with a low quiescent current, making it an ideal choice for portable and battery-powered equipment.
• Compact Package: The device comes in an 8-pin µMAX package, which is highly space-efficient and suitable for use in space-constrained applications.
