Frequently Asked Questions
What is the operating voltage range of the TPS2051BDBVR?
The TPS2051BDBVR operates with an input voltage range of 2.7V minimum to 5.5V maximum. This range makes it compatible with standard 3.3V and 5V power rails commonly used in USB interfaces, microcontroller systems, and portable battery-powered devices, providing broad applicability across a wide range of consumer and industrial applications.
Does the TPS2051BDBVR have adjustable current limiting?
No, the TPS2051BDBVR features a fixed (non-adjustable) current limit threshold. This fixed current limiting simplifies board design by eliminating external sense resistors or programming components. The fixed limit provides automatic protection against short circuits and overcurrent conditions without requiring any additional configuration, making it ideal for plug-and-play USB power switch applications.
What package does the TPS2051BDBVR come in?
The TPS2051BDBVR is housed in an R-PDSO-G5 package (JESD-30 code), which is a 5-pin plastic dual small outline package commonly known as SOT-23-5. This compact surface-mount package (DBV suffix) is ideal for space-constrained PCB layouts. The R suffix indicates tape-and-reel packaging for automated assembly, and JESD-609 code e4 confirms RoHS-compliant lead-free construction.
What are typical applications for the TPS2051BDBVR?
Primary applications include USB bus power switching and protection in computers, hubs, and docking stations; battery-operated portable device power management; 5V and 3.3V rail switching in embedded systems; power sequencing in multi-rail systems; and protected power delivery to expansion modules and peripheral devices. The current limit protects against overload and short-circuit conditions automatically.
How long is the TPS2051BDBVR expected to be available?
The TPS2051BDBVR has a YTEOL (Years To End of Life) rating of 15 years, indicating Texas Instruments plans to continue producing this component for at least 15 more years. This long product lifecycle makes it suitable for industrial, medical, and other applications where design stability and long-term component availability are critical requirements.
