The MAX801NCPA from Maxim Integrated is a high-performance microprocessor (µP) supervisory circuit designed to monitor power supplies in µP and digital systems. It provides excellent circuit reliability and low cost by eliminating external components and adjustments when used with +5V-powered circuits.

Key Features

• Precision Monitoring: The MAX801NCPA offers precision monitoring of +5V power supplies with a factory-trimmed reset threshold voltage. This ensures that your system operates reliably over temperature variations and initial accuracy of power supply voltages.
• Power-On Reset: Upon power-up, the device asserts a reset signal to the µP, holding it in reset for a minimum of 140ms after the power supply has reached a stable operating condition. This allows the system to initialize properly.
• Manual Reset Capability: A manual reset input is provided, allowing the user to initiate a system reset at any time. This is particularly useful for system debugging and testing.
• Low Power Consumption: The device is designed for low power consumption, drawing only 40µA of supply current, which is ideal for power-sensitive applications.
• Active-Low Reset: The reset output is active low, which is compatible with most microprocessors and other digital ICs.

Applications

The MAX801NCPA is versatile and can be used in a variety of applications, including:

• Computers and Controllers
• Intelligent Instruments
• Portable/Battery-Powered Equipment
• Embedded Systems

Package and Quality

The MAX801NCPA is available in an 8-pin DIP package, making it easy to integrate into your design. Maxim Integrated is known for its commitment to quality, and this product is no exception, ensuring reliable operation in the field.

Whether you are designing a new system or upgrading an existing one, the MAX801NCPA offers the features and reliability you need to ensure your system operates smoothly.
