Working Principles

The TC1271ARVCTTR is designed to monitor the supply voltage of a system. It compares the input voltage with a reference threshold and generates a reset signal when the voltage falls below the specified level. The reset signal remains active until the voltage rises above the threshold or a manual reset is triggered.

The device operates in a low-power mode, consuming minimal current while continuously monitoring the voltage. This makes it suitable for battery-powered applications where power efficiency is crucial.
