Maxim Integrated MAX814TCPA Microprocessor Supervisory Circuit

The Maxim Integrated MAX814TCPA is a highly reliable 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 in systems that require voltage monitoring and battery control functions.

This compact supervisory circuit ensures that your microprocessor will reset to a known state during power failures or whenever the voltage level drops below a predetermined threshold. The MAX814TCPA offers a variety of features that are essential for maintaining the integrity of the µP system and preventing data corruption.

Key Features:

• Precision Monitoring: The device features a precision voltage monitor that keeps a close eye on the system voltage levels. It has a factory-set reset threshold voltage, ensuring that the system is reset accurately and reliably whenever necessary.
• Manual Reset Capability: An additional feature includes a manual reset input that allows for a reset to be triggered with an external pushbutton or logic signal, providing extra control over the reset functionality.
• Power-On Reset: The MAX814TCPA generates a reset pulse when the power supply turns on, ensuring that the µP starts in a clean state every time.
• Low Power Consumption: Designed for energy-efficient operation, this supervisory circuit has a low quiescent current, making it suitable for battery-powered applications.
• Reset Timeout: It also features an internally set timeout period that ensures the reset signal is maintained long enough for the µP to initialize properly.

Applications:

The MAX814TCPA is versatile and can be used in a range of applications such as:

• Computers and Controllers
• Intelligent Instruments
• Critical µP Power Monitoring
• Portable/Battery-Powered Equipment

With its robust set of features, the MAX814TCPA from Maxim Integrated is an excellent choice for system designers looking for a simple, cost-effective solution to enhance the reliability and performance of their µP systems. Its small package and ease of integration make it an ideal component for a wide array of electronic products.
