Working Principles

The TC1271ASCVCTTR is a voltage supervisor IC that continuously monitors the supply voltage. It compares the supply voltage with a preset threshold voltage and generates a reset signal when the supply voltage falls below this threshold. The reset signal remains active until the supply voltage rises above the threshold for a specified timeout period. The IC also includes a manual reset input that can be used to assert a reset signal externally.
