MAX6318LHUK48BX-T - Maxim Integrated

The MAX6318LHUK48BX-T is a robust, high-precision microprocessor (µP) supervisory circuit designed by Maxim Integrated to monitor power supplies in digital systems. It provides significant reliability and accuracy in ensuring the proper function of µP systems by resetting these systems during power-up, power-down, and brown-out conditions.

Key Features:

• Voltage Monitoring: This device keeps a watchful eye on the system voltage, ensuring it remains within the acceptable range for reliable operation. It features a preset reset threshold voltage of 4.8V tailored for 5V-powered systems.
• Reset Timeout: The MAX6318LHUK48BX-T has an internally programmed timeout period which provides a reset signal for approximately 140ms after power-up, allowing the system to stabilize before normal operation commences.
• Manual Reset: An additional feature is the manual reset input, which allows for an external trigger to initiate a system reset. This is useful for system maintenance or emergency recovery procedures.
• Temperature Range: It operates over an extended industrial temperature range, from -40°C to +85°C, making it suitable for a wide range of applications in harsh environments.
• Package: The device comes in a compact SOT-23 package, which is ideal for space-constrained applications.
• Low Power Consumption: Designed with power efficiency in mind, this supervisory circuit has a low quiescent current, which helps to minimize the power drain on the system.

Applications:

The MAX6318LHUK48BX-T is versatile and can be used in a variety of applications that require reliable voltage monitoring and system reset functionality. These include:

• Computers and servers
• Embedded systems
• Portable/battery-powered devices
• Industrial equipment
• Telecommunication systems

With its precision voltage monitoring and reset capabilities, the MAX6318LHUK48BX-T from Maxim Integrated is an essential component for maintaining the integrity and smooth operation of µP systems.
