TPS2051BDBVR

Power Distribution Switches, Load Drivers Overview

The TPS2051BDBVR is a single-channel, current-limited power distribution switch manufactured by Texas Instruments. It operates within a supply voltage range of 2.7 V to 5.5 V and features an active-high enable input. The device provides a maximum output current of 500 mA with a fixed current limit threshold of 900 mA. It utilizes a SOT-23-5 surface-mount package and supports an operating temperature range from -40°C to +85°C.

Power Distribution Switches, Load Drivers Feature Summary

• Integrated current limiting protects against overload conditions by clamping output current to a safe level during faults.
• Controlled rise and fall times minimize inrush currents when connecting capacitive loads such as USB peripherals.
• Built-in thermal shutdown circuitry disconnects the load if excessive junction temperatures are detected.

Power Distribution Switches, Load Drivers Applications

• USB port protection in desktop and notebook computers
• Power distribution for high-definition digital televisions
• Set-top box power management systems

Power Distribution Switches, Load Drivers Procurement Notes

Verify the specific suffix 'G4' indicates RoHS compliance and manufacturing origin changes without altering electrical function. Confirm the package type matches the design requirements. Ensure the operating temperature range aligns with the target application environment. Check for obsolescence status as some variants may be discontinued.

Power Distribution Switches, Load Drivers Selection Notes

Select this component for applications requiring precise current limiting and soft-start capabilities. The 500 mA continuous rating suits standard USB peripheral loads. Consider the SOT-23-5 package for space-constrained designs. Verify that the 2.7 V minimum supply voltage meets the system's logic levels.

Power Distribution Switches, Load Drivers Part Context

This part belongs to the TPS20xxC family of USB power switches designed for robust fault protection. It integrates high-side switching with diagnostic features suitable for consumer electronics. The series offers various current ratings and package options to accommodate different power distribution needs.

Power Distribution Switches, Load Drivers Replacement Considerations

TPS2051BD is a pin-compatible alternative available in an SOIC-8 package. TPS2051BDBVT serves as a tape-and-reel variant of the same SOT-23-5 footprint. Verify package dimensions and thermal characteristics when substituting.
