Texas Instruments Incorporated have 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 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.
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..
