Maxim Integrated MAX6306UK31D3 Microprocessor Reset Circuit

The Maxim Integrated MAX6306UK31D3 is a highly reliable, low-power microprocessor (µP) supervisory circuit designed to monitor power supplies in µP and digital systems. It provides a significant level of protection against the unpredictable nature of system operation caused by power failures or glitches. This compact and efficient device is essential for maintaining the integrity and orderly control of digital systems upon startup and during operation.

Key Features

• Precision Monitoring: The MAX6306UK31D3 offers precision voltage monitoring, ensuring that the µP is reset to a known state during power-up, power-down, or brownout conditions. It features a factory-set reset threshold voltage of 3.08V, tailored for 3.3V powered systems.
• Low Power Consumption: Designed for power-sensitive applications, this device consumes a minimal amount of power, with a typical supply current of only 1µA, making it an ideal choice for portable and battery-operated equipment.
• Manual Reset Input: An additional feature is the manual reset input that allows for a system reset to be initiated manually, providing an extra layer of control for system operators or during maintenance procedures.
• Compact SOT23 Package: The MAX6306UK31D3 comes in a small SOT23 package, which is suitable for space-constrained applications, allowing for efficient use of PCB real estate.
• Robust Reset Outputs: It offers a choice of reset outputs. The reset output is guaranteed to be in the correct state for VCC down to 1V, ensuring reliable operation during low voltage conditions.
• Immune to Short VCC Transients: The circuit is designed to ignore short-duration transients on the VCC line, which helps prevent false triggering of the reset signal during fluctuations that are not long enough to affect system operation.

Applications

The MAX6306UK31D3 is versatile and can be used in a wide array of applications, including:

• Computers and Controllers
• Embedded Systems
• Battery-Powered Equipment
• Industrial Controllers
• Portable/Wearable Devices

With its robust design and precision voltage monitoring capabilities, the MAX6306UK31D3 from Maxim Integrated is an essential component for ensuring the reliable operation of microprocessor-based systems across various industries and applications.
