The MAX6339KUT+T is a microprocessor supervisor for monitoring and protection of system-level power supplies, and is part of the PMIC - Supervisors range of devices. It is capable of detecting a wide range of supply conditions, including overvoltage, undervoltage and brown-out conditions, protecting the system from potentially damaging conditions.

It’s important to note that the MAX6339KUT+T application field and working principle involve more than just single-line overvoltage/undervoltage/brown-out protection. This supervisor also has a dual reset pin, which can be used to assert two separate reset signals, allowing for an optimized reset solution depending on the voltage and current requirements of the system.

The MAX6339KUT+T contains two independent internal voltage references, and two independent input comparators, which can be configured to monitor two separate supply lines. This allows designers to easily monitor both the standard ATX 12V rail and the ATX main power rail, offering comprehensive protection across the board. With this supervisor, users can also set the OVUV and brown-out thresholds as desired, as well as the reset delay times, giving users plenty of options for making sure their system is protected.

The MAX6339KUT+T also features auto-power-source detection, which can detect the presence of an ATX main power rail or an ATX 12V rail, and automatically configure the backup voltage accordingly. This helps to prevent a situation where the supervisor starts to output reset signals when these rails are not present, as the supervisor will automatically detect what supply is present, and adjust its functioning accordingly.

One of the main advantages of the MAX6339KUT+T, is its low power consumption. With a typical operating current of 200 µA, it represents a highly efficient solution for power supervision and management. This means that it can be used in battery-powered applications, and will result in minimal power drain. It is also designed to be hot-plug safe, meaning that it will still operate correctly when power is applied or removed in the presence of load current, preventing any interruption of system operation during the event.

The MAX6339KUT+T is highly advanced for its size, and it uses advanced Supervisory features to ensure reliable power management in a range of applications. With its wide protection range, as well as its low power consumption and hot-plug safe operation, it offers a convenient and reliable solution for power management and system protection.
