Working Principles

The TPS2814PWRG4 operates as a high-side switch by controlling the flow of current between the input and output pins. When the enable pin is activated, the power switch turns ON, allowing current to flow from the input to the output. Conversely, deactivating the enable pin turns OFF the power switch, interrupting the current flow.

The device incorporates overcurrent protection, which monitors the current passing through it. If the current exceeds the set limit, the power switch is turned OFF to prevent damage to the system. Additionally, the thermal shutdown feature ensures that the device shuts down if the temperature exceeds a safe threshold, protecting it from overheating.
