Maxim Integrated MAX6414UK31/V+T Microprocessor Reset Circuit

The MAX6414UK31/V+T is a high-quality microprocessor (µP) supervisory circuit designed by Maxim Integrated to monitor power supplies in digital systems. It provides a reliable solution for ensuring that µPs and other digital systems reset properly during power-up, power-down, and brown-out conditions. This device is particularly useful in applications where precise voltage monitoring is critical for the performance and stability of the system.

With its compact SOT23-5 package, the MAX6414UK31/V+T offers a space-saving footprint for designs where board space is at a premium. The device features a factory-set reset threshold voltage of 3.1V, which is ideal for 3.3V-powered systems. This threshold ensures that the system will reset if the supply voltage drops below the specified level, preventing erratic operation due to insufficient power.

One of the key features of the MAX6414UK31/V+T is its low power consumption, drawing a minimal quiescent current of only 1.5µA. This makes it an excellent choice for portable and battery-operated devices where power efficiency is paramount. Additionally, the device has an active-low, push-pull RESET output, which remains asserted for a minimum of 140ms after VCC has risen above the reset threshold, providing ample time for the system to stabilize before the processor starts operating.

The MAX6414UK31/V+T also includes a manual reset input that allows the user to trigger a system reset with an external signal. This feature is particularly useful for initiating a system reset without cycling the power supply, which can be beneficial during system maintenance or troubleshooting.

Designed for robust operation, the MAX6414UK31/V+T operates over a wide temperature range of -40°C to +125°C, ensuring reliable performance in a variety of environmental conditions. Whether used in complex digital systems, portable devices, or industrial controls, the MAX6414UK31/V+T from Maxim Integrated provides the essential protection needed for stable and reliable system operations.

Overall, the MAX6414UK31/V+T is a testament to Maxim Integrated's commitment to delivering high-quality, precision-engineered solutions for digital system management and supervision.
