Load switches
Make the switch from discrete to integrated
Load switches are a simple, cost-effective way to turn on and off your power rails. Our broad portfolio includes extensive current, package, and timing options. Plus, our easy-to-use parametric search tool will quickly help you find the solution to reduce your shutdown current or reduce the BOM count in your design.
Flexible timing
Options include a fixed or adjustable linear rise time. This can be used to manage inrush current or power sequence loads
Broad current range
Select a switch to support your low, mid or high current rails
Featured load switches
TPS22918
TPS22918 is a 5.5V, 2A, 52m Ω load switch with adjustable rise time and output discharge, allowing design flexibility. Interface directly with low-voltage control signals with a small sized switch.
TPS22965-Q1
TPS22965-Q1 is a 5.5V, 4A, 16mΩ automotive high-side load switch with adjustable rise time & quick output discharge. This is in a small package solving your power dissipation concern.
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.
