Maxim Integrated MAX819MCUA+ Microcontroller Supervisor IC

The Maxim Integrated MAX819MCUA+ is a highly reliable microcontroller (MCU) supervisory circuit designed to monitor power supplies in microprocessor and digital systems. It provides excellent circuit reliability and low cost by eliminating external components and adjustments when used in conjunction with +5V-powered circuits.

This compact supervisor IC is packed with features to ensure your systems operate smoothly under varying power conditions. The MAX819MCUA+ offers a combination of functions such as power-on reset control, watchdog timer, and manual reset capability. These features make it an ideal choice for use in complex microcontroller-based applications, including portable devices, computers, embedded systems, and other microprocessor equipment.

Key Features:

• Power-On Reset: The device generates a reset signal when the supply voltage drops below the reset threshold, ensuring the MCU starts up in a known state every time.
• Watchdog Timer: A watchdog timer is built-in to help recover from a software failure. If the microprocessor or software becomes unresponsive, the watchdog timer will reset the system automatically.
• Manual Reset Input: An external input is provided to manually reset the system, allowing for greater control and debugging capabilities.
• Voltage Monitoring: Precision monitoring of the +5V power-supply voltage is enabled with a factory-set reset threshold voltage.
• Low Power Consumption: The device operates with low power consumption, making it suitable for battery-operated applications.
• Compact Package: The MAX819MCUA+ comes in a small 8-pin µMAX package, saving valuable board space.
• Temperature Range: It operates over the extended temperature range (-40°C to +85°C), ensuring reliability across various environments.

Integrating the MAX819MCUA+ into your design simplifies the task of system monitoring, providing peace of mind that your system will remain stable and reliable. Its combination of reset logic, watchdog functionality, and manual reset input, all within a small footprint, make it a versatile and essential component for any microcontroller-based system.

With Maxim Integrated's reputation for quality and reliability, the MAX819MCUA+ supervisor IC is a smart choice for designers looking to enhance system integrity and prevent data corruption due to unpredictable power supply conditions.
