Working Principles

The TPS2331IPWR operates as a power-distribution 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 pass from the input to the output. The device continuously monitors the output current and temperature. If the current exceeds the set threshold or the temperature rises above the specified limit, the power switch is disabled to protect the load and prevent damage.
