Working Principles

The TPS3813I50DBVRG4 is a voltage supervisor IC that monitors the supply voltage of a system. It compares the monitored voltage with a programmable threshold voltage. When the supply voltage drops below the threshold, the IC asserts a reset signal to the microcontroller or digital system, indicating a power failure or low voltage condition.

The reset timeout period can be programmed using external components, allowing for customization based on specific system requirements. The IC also provides a manual reset input, which allows for immediate system reset when triggered.
