Working Principles

The MAX6831SDUT+T is a voltage supervisor IC that monitors the supply voltage and generates a reset signal when the voltage falls below a certain threshold. It operates within a wide supply voltage range of 1.5V to 5.5V, making it suitable for a variety of applications.

The device features an adjustable threshold voltage, allowing the user to set the desired voltage level at which the reset signal is triggered. This flexibility enables compatibility with different system requirements.

Additionally, the MAX6831SDUT+T offers configurable reset timeout periods. These timeout periods determine the duration for which the reset signal remains active after the supply voltage rises above the threshold. The available options allow customization based on specific application needs.

The IC also includes a manual reset input (MR), which allows the user to manually assert or deassert the reset signal. This feature provides control over the system's operation and facilitates system testing and debugging.

The MAX6831SDUT+T consumes low quiescent current, making it suitable for battery-powered or energy-efficient devices. Its open-drain reset outputs enable easy interfacing with other components in the system.
