TPD4S014DSQR

Overview

The TPD4S014DSQR is a specialized integrated circuit designed for complete USB port protection, manufactured by Texas Instruments. It integrates ESD suppression diodes, overvoltage protection control, and a low on-resistance switch within a single chip. The device features four channels with a typical capacitance of 1.6 pF and operates at a working voltage of 5 V. It provides robust protection against electrostatic discharge up to ±15 kV contact and air gap discharge. The component is housed in a compact 10-WSON package (2x2 mm) with an exposed pad, suitable for surface mount assembly. It supports data rates compatible with USB 2.0 high-speed transmission.

Feature Summary

• Integrated ESD protection rated for ±15 kV contact and air discharge per IEC 61000-4-2
• Built-in overvoltage protection controller with UVLO and thermal shutdown capabilities
• Low on-resistance FET switch supporting charging currents greater than 2 A
• Compact 10-WSON (2x2 mm) package with 1.6 pF typical capacitance for high-speed data integrity

Applications

• Cell Phones
• Media Players
• Portable electronic devices requiring USB 2.0 interface protection

Procurement Notes

Verify the specific ordering suffix DSQR corresponds to the Tape & Reel packaging configuration as indicated in supplier documentation. Confirm that the 10-WSON package dimensions match the design footprint requirements. Ensure compliance with RoHS directives and moisture sensitivity levels specified in the manufacturer's datasheet before integration into production assemblies.

Selection Notes

Select this component when a unified solution for ESD, overvoltage, and power switching is required for USB ports. The low capacitance value of 1.6 pF makes it suitable for high-speed data lines where signal integrity is critical. Consider the 10-WSON package size for applications with strict space constraints. Verify that the operating temperature range of -40°C to +85°C meets the environmental conditions of the target application.

Part Context

This part belongs to the TPD4S014 series from Texas Instruments, which focuses on comprehensive protection for USB interfaces. The DSQR suffix typically denotes the reel packaging format used for automated surface-mount assembly. It serves as a direct replacement for discrete protection components, simplifying the bill of materials and reducing board space usage in portable electronics.

Replacement Considerations

Check for pin-compatible alternatives within the same Texas Instruments family or other manufacturers offering similar 4-channel USB protection controllers. Ensure that any substitute maintains the 1.6 pF capacitance limit and ±15 kV ESD rating to preserve system reliability.
