Working Principles

The TPS2413DR operates as a high-side power switch, controlling the flow of current from the input to the output. When the enable pin is activated, the power switch turns on, allowing current to pass through. The integrated current-limiting function ensures that the current does not exceed the set limit, protecting the load or system from damage. In case of overcurrent or excessive temperature, the device triggers the fault indicator and activates the thermal shutdown feature to prevent further operation until the fault condition is resolved.
