Maxim Integrated MAX805SCSA+ Microprocessor Supervisory Circuit

The MAX805SCSA+ from Maxim Integrated is a highly reliable microprocessor (µP) supervisory circuit designed to monitor power supplies in µP and digital systems. It provides a significant level of system integrity by ensuring that the µP boots up in a predictable state every time. This compact device is essential for managing system resets and power-on reset functionality.

The MAX805SCSA+ provides a multitude of features making it an excellent choice for applications requiring precise voltage monitoring and reset functions. It is particularly suitable for portable/battery-powered devices, computers, controllers, and intelligent instruments.

Key Features:

• Precision Monitoring: Accurate monitoring of 5V, 3.3V, 3V, and other voltage levels.
• Reset Timeout: Offers a reset timeout of 140ms min to ensure proper system reset.
• Low Power Consumption: Ideal for power-sensitive applications with its low supply current of 20µA.
• Versatile Voltage Thresholds: Includes factory-trimmed reset thresholds for various applications.
• Manual Reset Feature: Provides a manual reset input for added control.
• Compact Package: Available in a space-saving 8-pin SO package.

Applications:

• Portable Devices
• Embedded Systems
• Computers and Servers
• Data Storage Systems
• Industrial Controllers

The MAX805SCSA+ ensures that if the supply voltage drops below a preset threshold, the reset output will be asserted, which holds the µP in a reset state for a minimum of 140ms after the supply voltage exceeds the reset threshold. This feature protects the µP from operating under unpredictable conditions that could lead to system errors or data corruption.

With its robust set of features and compact design, the MAX805SCSA+ is a critical component for any system requiring reliable voltage monitoring and reset capabilities. Maxim Integrated's commitment to quality and performance makes this supervisory circuit a smart choice for safeguarding your digital systems.
