Working Principles

The TPS22917DBVT operates as a load switch by controlling the flow of current from the input voltage (IN) to the output voltage (OUT). The enable pin (EN) is used to turn the load switch on or off. When the EN pin is high, the load switch is enabled, allowing current to flow from IN to OUT. Conversely, when the EN pin is low, the load switch is disabled, cutting off the current path.

The TPS22917DBVT incorporates low RDS(on) MOSFETs, which minimize power losses during operation. It also features adjustable current limit functionality, enabling users to set the desired current threshold for load control.
