Working Principles

The STM6822TWY6F is a voltage supervisor IC that monitors the supply voltage of a system. When the supply voltage falls below the programmed threshold voltage, the RESET pin is asserted low, indicating a reset condition. The reset signal remains active until the supply voltage rises above the threshold voltage for the specified timeout period. The CT pin is used to connect an external capacitor that determines the timeout period.
