Maxim Integrated MAX6747KA23 Microprocessor Supervisory Circuit

The MAX6747KA23 from Maxim Integrated is a highly reliable and compact microprocessor (µP) supervisory circuit designed to monitor power supplies and microprocessor activity in digital systems. It provides excellent circuit reliability and low cost by eliminating external components and adjustments when used in system monitoring applications.

This supervisory circuit ensures that the microprocessor is reset to a known state during power-up, power-down, or brown-out conditions. The MAX6747KA23 operates over a wide voltage range and offers several key features that make it an ideal choice for system management in complex electronics.

Key Features:

• Reset Output: The device provides a reset output during power-up, power-down, and brown-out conditions. The reset signal remains asserted for a minimum timeout period after V_CC becomes valid to ensure proper system reset.
• Factory-Trimmed Reset Thresholds: The reset thresholds are factory-trimmed for accuracy, which can help to simplify the design process and reduce time to market.
• Manual Reset Input: A manual reset input is provided, allowing for a reset to be triggered with an external switch or logic signal.
• Low Supply Current: The device has a low supply current, making it suitable for battery-operated applications where power efficiency is critical.
• Immune to Short V_CC Transients: The MAX6747KA23 is designed to be immune to short V_CC transients, ensuring reliable operation even in noisy environments.
• Compact SOT23 Packaging: The small SOT23 package allows for a compact footprint on PCBs, making it well-suited for space-constrained applications.

Applications:

The MAX6747KA23 is versatile and can be used in a variety of applications, including:

• Computers and Servers
• Embedded Systems
• Portable/Battery-Powered Equipment
• Network and Telecommunications
• Industrial Controllers

With its precision monitoring capabilities and robust feature set, the MAX6747KA23 from Maxim Integrated is an excellent choice for ensuring system stability and reliability in a wide range of electronic systems.
