TI introduces the industry's smallest High-Speed USB protection device for portable applications

First device to integrate protection against ESD, over-temperature, over-voltage and under-voltage events in a single package

DALLAS, Sept. 15, 2011 /PRNewswire/ -- Texas Instruments Incorporated (TI) (NYSE: TXN) today introduced the industry's first device to integrate four types of USB 2.0 chip protection in a single package. The TPD4S014 provides a high level of protection against electrostatic discharge (ESD) and is the industry's smallest USB protection device for all four USB channels, measuring only 2 mm x 2 mm. Should the device junction temperature exceed 150 degrees Celsius, the switch turns off to the power rail, thus protecting against over-temperature conditions. To protect the power rail from a moving voltage line, the load switch in the TPD4S014 immediately opens, preventing under- or over-voltage if the power supply rail drops lower than 2.8 V or higher than 6.15 V. To download a data sheet or order samples see: www.ti.com/tpd4s014-pr.

Designers can implement the TPD4S014 in many design configurations that require a small footprint, such as cell phones, e-books, portable media players and digital cameras, tablets, embedded computing, portable navigation, portable land surveying, and portable test and measurement.

TPD4S014 key features and benefits

  • First device to offer four types of protection in a single compact package: over-voltage, under-voltage, over-temperature and ESD.
  • Industry's smallest USB protection device for all four USB channels, 75 percent smaller than competing devices that only offer ESD protection.
  • Offers protection for all four High-Speed USB (USB 2.0) channels: D+, D-, VBUS and ID.
  • Complies with the highest level of ESD protection, with immunity of +8-kV contact discharge and +15-kV air-gap discharge per IEC61000-4-2 system-level ESD immunity testing.
  • Compatible with both Full Speed and High Speed, supporting data rates of up to 480 Mbps..

Availability and pricing

The TPD4S014 comes in an 10-pin, 4-mm2 DSQ SON package and is in full production now. The TPD4S014 is available from TI and authorized distributors with the suggested resale price of $0.55 in quantities of 1,000.
