The MAX6800UR40D3+T is a PMIC (Power Management Integrated Circuit) Supervisors developed by Maxim Integrated, a leader in analog and mixed-signal semiconductor technology. The MAX6800UR40D3+T supervisor is designed to protect embedded systems from power outages and brownouts, while providing accurate voltage detection with minimal external components. It features a 10μA supply current and wide supply voltage (1.7V - 5.5V) allowing it to be used in a wide variety of applications.

The MAX6800UR40D3+T is well suited for embedded system applications such as industrial control, automotive and consumer applications where power losses are a major concern. It provides protection from short-term power drops, brownouts, and over-voltage events. It also helps extend battery life in portable device applications. In addition to providing voltage supervisor functions, such as reset generation, the MAX6800UR40D3+T also integrates a watchdog timer for system monitoring, providing a reset output when the timer expires.

The working principle of the MAX6800UR40D3+T is based on voltage detection and regulation. It senses the input voltage and compares it with a programmable voltage reference. If the input voltage falls below a certain threshold, the supervisor output is toggled, which can then be used to reset embedded system components. There is an auto-restart feature that returns the system to its power-on state at the end of the reset period. The MAX6800UR40D3+T is designed to be powered by 3V to 5.5V supplies so it can be used in many applications. With its low supply current of 10μA, it minimizes power consumption while providing reliable system monitoring.

The MAX6800UR40D3+T can be used to detect voltage fluctuations in applications such as automotive, industrial, and consumer applications. The device can automatically detect faults in the system and issue reset signals when appropriate. It also helps extend battery life when used in portable devices by quickly detecting and responding to voltage drops. This eliminates the need for frequent battery replacements and helps preserve the life of the battery. The device also provides an interface for external components such as an LED indicator.

In addition to voltage monitoring and regulation, the MAX6800UR40D3+T also provides an integrated watchdog timer for system monitoring. The timer can be programmed for periods between 100ms and 3s, and it can be used to detect faults that might require a system reboot. The device can also be configured to reset after a period of delay or in response to an external reset signal. The MAX6800UR40D3+T is protected against over- and under-voltage events and is also protected against false triggering and switch bounce.

Overall, the MAX6800UR40D3+T is an extremely effective voltage supervisor designed for a wide range of applications. It offers an efficient solution to power monitoring, reset generation, and system monitoring, while providing protection against over- and undervoltage events. The device’s low supply current ensures minimal power consumption, making it an ideal choice for power management needs. The integrated watchdog timer provides a reliable way to detect system faults, helping to ensure that systems remain up and running. With such high performance and low power requirements, the MAX6800UR40D3+T is an excellent choice for any embedded system.
