The MAX814KCSA+ is a highly integrated microprocessor (µP) supervisory circuit designed by Maxim Integrated 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 offers several key features that make it ideal for a broad range of applications, including computers, controllers, intelligent instruments, and critical µP power monitoring. The MAX814KCSA+ ensures that the µP is reset to a known state during power-up, power-down, and brownout conditions. Additionally, it monitors the power supply voltage and maintains a reset output until the supply voltage reaches a stable operating level and maintains it for a specified period, ensuring a proper system startup.

Key Features:

• Precision Monitoring: It features precision voltage monitoring, typically 4.65V, which is ideal for 5V power supplies.
• Reset Timeout: The device offers an adjustable reset timeout delay, which can be set by an external capacitor.
• Manual Reset: A manual reset feature is included, allowing for a reset to be triggered with a simple push-button.
• Low Power Consumption: The MAX814KCSA+ is designed for low power consumption, making it suitable for battery-operated applications.
• Compact Package: It is available in a space-saving 8-pin SO package, allowing for efficient use of board space.

The MAX814KCSA+ operates over a wide temperature range, from -40°C to +85°C, making it reliable in various environmental conditions. Its robust design and comprehensive feature set ensure that it is a go-to solution for system designers looking to enhance system integrity and prevent data corruption due to power anomalies.

With Maxim Integrated's commitment to quality, the MAX814KCSA+ supervisory circuit represents a dependable choice for safeguarding your critical microprocessor-based systems.
