What are load switches?
Integrated load switches from the TPS229xx family are integrated electronic relays used to turn on and 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. For a higher level of input or output power protection, check out our eFuse devices, which include features such as overvoltage shutdown, current limiting, and short circuit protection.
