Working Principles

The TC54VN2902ECB713 is designed to monitor the supply voltage and provide a reset output signal when the voltage falls below a certain threshold. It operates by comparing the supply voltage with an internal reference voltage. When the supply voltage drops below the selected threshold, the reset output is activated, indicating a power failure or low voltage condition. The manual reset input allows for external control of the reset signal.
