Getting to know load switches
What are load switches?
Integrated load switches from the TPS229xx family are integrated electronic relays used to turn on and turn off power rails. Most basic load switches consist of four pins: input voltage, output voltage, enable, and ground. Shown below is a block diagram of a basic load switch.

Why do you need load switches?
Texas Instruments Load Switches can be used for a variety of applications from power savings to power distribution and power sequencing. Additionally, integration will reduce overall BOM count and solution size, as well as adding additional protection features such as Quick Output Discharge, Reverse Current Protection, and Current Limiting.
