Maxim Integrated MAX808LESA+T Microprocessor Reset Circuit

The MAX808LESA+T is a highly efficient microprocessor (µP) supervisory circuit designed and manufactured by Maxim Integrated, a renowned leader in the development of integrated circuits. This compact and reliable component is specifically engineered to monitor power supplies in µP and digital systems, providing a significant enhancement to the system reliability and operational stability.

This supervisory circuit is essential for managing the reset function for microprocessors, ensuring that the µP starts up in a known state. The MAX808LESA+T asserts a reset signal whenever the VCC supply voltage declines below the factory-set reset threshold level. The reset output remains asserted for a preset timeout period after VCC has risen above the reset threshold, providing ample time for the system to stabilize.

Key features of the MAX808LESA+T include:

• Factory-Set Reset Thresholds: This device comes with preset voltage threshold levels suitable for most applications, eliminating the need for external components to set the operating parameters.
• Low Power Consumption: With its low supply current draw, it is an excellent choice for portable and battery-operated applications where power efficiency is crucial.
• Guaranteed Reset Valid to VCC = 1V: The MAX808LESA+T ensures reliable operation by providing a valid reset signal even at very low voltage levels, down to 1V.
• Immune to Short VCC Transients: Fast transients on the VCC line will not generate false resets, maintaining the integrity of the system's operation.
• Compact SOT-23 Packaging: Its small footprint makes it ideal for space-constrained applications, without compromising on performance.

The MAX808LESA+T is a versatile component that can be used in a variety of applications, including computers, controllers, intelligent instruments, and portable/battery-powered products. Its robust design ensures that it is capable of handling the demanding requirements of modern electronic devices, providing a simple yet effective solution for system reset and power monitoring needs.

With its ease of integration and proven reliability, the MAX808LESA+T from Maxim Integrated is an indispensable component for designers looking to enhance the performance and stability of their digital systems.
