Working Principles

The TLC7733IDRG4 is a voltage supervisor IC that monitors the supply voltage and generates a reset signal when it falls below a user-defined threshold. It utilizes a precision voltage reference to compare the supply voltage with the threshold voltage set by the THRESH pin. When the supply voltage drops below the threshold, the RESET pin is asserted low, indicating a power-on reset condition. The open-drain output allows easy interfacing with other devices.
