The MAX6349YLUT+ is a precision microprocessor (µP) supervisory circuit designed by Maxim Integrated to monitor power supplies in digital systems. It provides excellent circuit reliability and low cost by eliminating external components and adjustments when used in systems that require voltage monitoring.

This compact supervisory IC is ideal for monitoring 3.3V, 3V, and other voltage rails, ensuring that the system's microprocessor is reset to a known state during a power failure. With its wide operating voltage range and low supply current, the MAX6349YLUT+ is suitable for use in a variety of applications, including portable devices, computers, controllers, and intelligent instruments.

Key Features:

• Precision Monitoring: The device features a factory-trimmed reset threshold voltage, which helps maintain system integrity by providing a predictable output during power fluctuations.
• Low Power Consumption: It has a low supply current of 1.2µA (typical), making it an energy-efficient choice for battery-powered applications.
• Reset Output: The reset output remains asserted for a minimum of 140ms (typical) after VCC has risen above the reset threshold, ensuring a proper system reset.
• High Threshold Accuracy: The reset threshold accuracy is ±1.5% over temperature, which guarantees reliable monitoring under varying conditions.
• Compact Package: Offered in a small, 6-pin SOT23 package, the MAX6349YLUT+ saves space on PCBs and is ideal for space-constrained applications.
• Temperature Range: It operates over an extended temperature range of -40°C to +125°C, accommodating a wide range of environmental conditions.

Applications:

• Portable/Battery-Powered Equipment
• Embedded Systems
• Data Storage Equipment
• Telecommunications Systems
• Industrial Controllers

The MAX6349YLUT+ is a versatile and reliable solution for systems that require accurate voltage monitoring to protect against data loss, system failures, and hardware damage. Its precision and low power consumption make it a top choice for designers looking to enhance the safety and efficiency of their systems.
