The MAX6384XS26D3 is a highly reliable, low-power 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 system monitoring applications. This device is particularly suitable for portable electronics, computers, controllers, and intelligent instruments where maintaining the correct operation of the μP during power fluctuations is critical.

This supervisory circuit operates by providing a reset signal to the connected μP during power-up, power-down, and brownout conditions. When the monitored power supply voltage falls below a preset threshold, the MAX6384XS26D3's active-low reset output is asserted to prevent the μP from executing erroneous instructions. This reset signal remains asserted for a minimum timeout period after the supply voltage exceeds the reset threshold, ensuring the μP has adequate time to stabilize.

Key Features of MAX6384XS26D3

• Precision Factory-Set Reset Thresholds: The device comes with factory-set reset thresholds tailored to the 2.63V level, ideal for 2.7V to 3.3V powered circuits.
• Low Power Consumption: With its low power draw, the MAX6384XS26D3 is an excellent choice for battery-operated devices, contributing to longer battery life and improved energy efficiency.
• Manual Reset Input: A manual reset input is provided, allowing for a system reset to be initiated by external hardware or software controls.
• Immune to Short VCC Transients: The device is designed to ignore short transients on the VCC line, preventing unnecessary resets due to brief power glitches.
• Compact Form Factor: The MAX6384XS26D3 is available in a small, surface-mount SC70 package, making it suitable for space-constrained applications.

Applications

The MAX6384XS26D3 is versatile and can be used in a wide range of applications. Its primary use is to ensure system stability by providing a reset signal to μPs during power disturbances. This makes it ideal for:

• Portable/Battery-Powered Equipment
• Computers and Servers
• Embedded Systems
• Data Storage Systems
• Medical Devices
• Industrial Controllers

Overall, the MAX6384XS26D3 from Maxim Integrated is a robust solution for system monitoring, offering a blend of precision, low power consumption, and ease of integration, all of which contribute to a more reliable and efficient electronic system design.
