What are the key features of TPS2068DG4?

Single-channel high-side switch with 2.1A continuous current capacity at 5.5V for USB power applications
Integrated undervoltage lockout (UVLO) protection prevents load activation during power rail instability
Compact 8-pin SOIC (SOIC-8) package enables space-efficient PCB integration in tight USB power distribution designs

What is TPS2068DG4 used for?

TPS2068DG4 is well-suited for USB bus power switching in laptop docking stations, USB hubs, and consumer electronics requiring controlled power delivery. Its high-side switch topology and current-limiting capability make it ideal for protecting USB downstream ports from overcurrent faults. Industrial designs also leverage this device in 5V rail power distribution where load sequencing and protection are critical.

Frequently Asked Questions

What is the maximum continuous output current supported by TPS2068DG4?

TPS2068DG4 supports a maximum continuous output current of 2.1A at a supply voltage up to 5.5V, making it suitable for standard USB 2.0 and USB 3.0 power delivery applications that require reliable current handling on a single channel.

How does the undervoltage lockout feature in TPS2068DG4 protect connected USB loads?

The integrated UVLO circuit monitors the supply rail and holds the output switch open until the input voltage reaches a stable threshold, preventing loads from operating at insufficient voltage levels. This protects sensitive downstream devices from brown-out conditions during power-up sequences in systems with 5V rails.

Which PCB form factor does TPS2068DG4 use, and how does it compare to SOT-23 alternatives?

TPS2068DG4 uses an 8-pin SOIC package measuring approximately 4.9mm x 3.9mm, which provides larger pad sizes and easier hand-soldering compared to smaller SOT-23 packages, though it occupies slightly more board area. This makes it a practical choice when thermal dissipation at 2.1A output current is a design concern.

Can TPS2068DG4 be used in industrial USB charging station designs?

Yes. TPS2068DG4 operates across a 2.7V to 5.5V input range and supports 2.1A per channel, covering the power demands of USB charging ports in industrial kiosks, test equipment, and embedded computing platforms. Its SOIC-8 footprint and single-channel architecture simplify layout when multiple independent switched outputs are needed.
