Maxim Integrated MAX6413UK29+T Microprocessor Reset Circuit

The Maxim Integrated MAX6413UK29+T 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 system reliability and accuracy required in critical applications. This device is particularly well-suited for portable and battery-powered electronics due to its low power consumption and compact SOT23 packaging.

Key Features

• Voltage Monitoring: The MAX6413UK29+T monitors the system voltage and keeps the µP in reset mode during power-up, power-down, and brownout conditions. It ensures that the µP starts up in a known state every time.
• Reset Threshold: It has a preset reset threshold voltage of 2.93V, optimized for 3V systems, which is crucial for maintaining system stability.
• Low Power Consumption: With its low supply current of only 1.2µA, it is an ideal choice for power-sensitive applications.
• Manual Reset Input: A manual reset input is provided, allowing the user to trigger a reset with an external push-button or logic signal.
• Reset Output: The device offers an active-low, open-drain reset output, which remains asserted for a minimum of 140ms after VCC has risen above the reset threshold, ensuring proper system reset.
• High-Temperature Operation: The MAX6413UK29+T is designed to operate over a wide temperature range of -40°C to +125°C, making it suitable for industrial applications.
• Compact Size: Its small SOT23-5 package saves space on PCBs, a valuable feature for space-constrained designs.

Applications

The MAX6413UK29+T is versatile and can be used in a variety of applications, including:

• Computers and Servers
• Embedded Systems
• Battery-Powered Equipment
• Industrial Controllers
• Portable Consumer Electronics

Overall, the Maxim Integrated MAX6413UK29+T is an essential component for systems that require accurate and reliable monitoring of the supply voltage to ensure proper operation and to protect against data corruption during adverse power conditions.
