Maxim Integrated MAX6424UK31+T Microprocessor Reset Circuit

The Maxim Integrated MAX6424UK31+T is a highly reliable, low-power microprocessor (µP) supervisory circuit designed 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 with 3.1V-powered circuits.

One of the key features of the MAX6424UK31+T is its ability to provide a precision voltage monitoring solution. It ensures that the µP resets cleanly during power-up, power-down, and brown-out conditions. The reset output from the device remains asserted for a minimum timeout period after V_CC has risen above the reset voltage threshold, ensuring the system has sufficient time to stabilize before the processor starts operating.

Key Features:

• Precision Factory-Set V<sub>CC Reset Thresholds: The device comes with factory-set reset thresholds suitable for operation with a 3.1V power supply, ensuring compatibility with a range of low-voltage applications.
• Low Power Consumption: With its low power consumption, the MAX6424UK31+T is ideal for use in portable and battery-powered equipment, helping to extend battery life and reduce power waste.
• Manual Reset Input: The inclusion of a manual reset input provides a convenient way to initiate a system reset with an external button or switch.
• Immune to Short V<sub>CC Transients: The device is designed to ignore short transients on the V_CC line, which helps to prevent unnecessary resets due to brief power supply disturbances.
• Compact SOT23 Packaging: Housed in a small SOT23 package, the MAX6424UK31+T saves valuable board space, making it an excellent choice for space-constrained applications.

The MAX6424UK31+T is an ideal solution for systems that require a reliable reset mechanism to maintain proper operation. Whether used in computers, controllers, intelligent instruments, or portable consumer products, this reset circuit from Maxim Integrated provides the necessary protection against unpredictable power supply conditions, ensuring that your system remains functional and reliable.

With its combination of features, the MAX6424UK31+T represents a robust solution for system designers looking to enhance the operational stability of their digital systems without incurring additional costs or complexity.
