Working Principles

The TPS2042BDGNRG4 operates by controlling the flow of current between the input and output pins. When the EN pin is activated, the power switch turns on, allowing current to flow from the input to the output. If an overcurrent condition is detected, the device activates the FLT pin, indicating a fault condition. The TPS2042BDGNRG4 automatically limits the current to protect the load and itself from damage.
