Maxim Integrated MAX808NCSA Microprocessor Reset Circuit

The Maxim Integrated MAX808NCSA is a highly efficient microprocessor (µP) supervisory circuit designed to monitor power supplies in µP and digital systems. It provides a significant level of protection against low-voltage, ensuring the proper operation of the system in the event of power failures or unexpected voltage dips.

This compact device is engineered to assert a reset signal whenever the VCC supply voltage declines below a preset threshold, maintaining it until the supply voltage recovers and stabilizes. The reset signal keeps the µP within the system in a reset state, preventing any malfunction or erroneous operations that could arise from inadequate power levels.

Key Features:

• Precision Voltage Monitoring: The MAX808NCSA offers precise monitoring of the power supply with a factory-set reset threshold voltage, ensuring reliable operation.
• Low Power Consumption: With its low power design, this device is an ideal choice for power-sensitive applications, contributing to the overall efficiency of the system it is part of.
• Manual Reset Capability: The inclusion of a manual reset input allows for a reset to be triggered with an external switch or logic signal, providing additional control to the system operators.
• High Reset Output Sink Current: The output can sink a significant current, making it suitable for resetting even power-hungry microprocessors or digital ICs.
• Compact Package: Housed in a space-saving 8-pin SO package, the MAX808NCSA is ideal for systems where board space is at a premium.

Applications:

• Computers and Servers
• Embedded Systems
• Portable/Battery-Powered Equipment
• Data Storage
• Telecommunications

The Maxim Integrated MAX808NCSA is a reliable and essential component for maintaining system integrity. Its ability to ensure a stable and secure operating environment for microprocessors makes it a go-to solution for engineers looking to safeguard their digital systems against the perils of unpredictable power supplies.
