Key Features
- Triple-channel load switch enabling independent control of three power rails from a single IC
- Adjustable current-limit threshold allowing flexible overcurrent protection tailored to specific load requirements
- Wide supply voltage range of 2.7V to 5.5V compatible with 3.3V and 5V system power buses
- Integrated overcurrent and thermal protection for robust fault management without external components
- Compact 20-pin HTSSOP package with exposed pad for efficient thermal dissipation
Applications
The TPS2228PWPG4 is ideal for USB power distribution systems, docking stations, and portable computers where multiple load switches are needed to sequence and protect power delivery to peripherals. It is also used in industrial equipment and embedded systems requiring precise current limiting and hot-swap capability across three independent channels. The adjustable threshold and fault reporting features make it well suited for applications where overcurrent events must be detected and reported to a host controller.
