Working Principles

The TPS3430WQDRCRQ1 operates by comparing the input voltage with the threshold voltage set by the user. When the input voltage exceeds the threshold, the output pin is pulled low, indicating a fault condition or triggering an action. The hysteresis feature ensures that the output remains stable even in the presence of noise or voltage fluctuations.
