Latest eFuse protection ICs for USB Type-C port protection

Littelfuse, Inc offers its latest addition to the eFuse Protection ICs product line of versatile circuit protection devices, the LS05006VPQ33.

This new IC's innovative design protects USB Type-C ports against short circuits, overvoltage, and ESD. The device is a highly integrated protection IC for Type-C PD Vbus fast to CC/SBU with a 28V max and 8KV IEC-61000-4-2 ESD capability.

The eFuses are excellent for use in many USB Type-C applications, including Notebooks, Desktops, Monitors, Industrial PCs, POS, Smartphones, Tablets, and USB Type-C PD docking stations.

"The LS05006VPQ33 is an extension of the Littelfuse eFuse protection IC solutions, and it is our first eFuse to support 20 V short, overvoltage, and system ESD protection for signal pins," said Bernie Hsieh, APM of Protection Semiconductor Business at Littelfuse. "The LS05006VPQ33 provides better reliability, longer life, lower repair costs, and compact product size. It also works well with the LS2406ERQ23 eFuse for Vbus 20V, 5A protection."

The device's design solves the critical problem of protecting low-voltage silicon circuits in USB Type-C controllers from overvoltage, short circuits, and ESD strikes. Many USB Type-C products do not meet the Type-C specification, and some adapters that only provide 20V to Vbus can cause short circuits due to pin issues, twisting, or moisture. Without protection, downstream low-voltage circuits can be damaged. The LS05006VPQ33 ensures that downstream low-voltage circuits are safeguarded against overvoltage and IEC61000-4-2 ESD strikes.

As well as better reliability, longer life, and lower repair costs, the device also provides other competitive advantages. It supports higher Vmax (28V) and higher ESD rating at SBU with 8KV ESD contact compared to other available solutions. These benefits make it the ideal solution for electronics engineers seeking a reliable and efficient USB Type-C port protection solution.
