MANUFACTURED BY Littelfuse

This new eFuse protective integrated circuit's (IC) innovative design protects USB Type-C ports against short circuits, overvoltage, and electrostatic discharge (ESD). The LS05006VPQ33 is a highly integrated protection IC for Type-C PD Vbus short to CC/SBU with 28 V max and 8 KV IEC-61000-4-2 ESD capability. The eFuse LS05006VPQ33 protection ICs are ideal for use in a wide range of USB Type-C applications, including:

• Notebooks

• Desktops

• Monitors

• Industrial PCs

• Point of sales

• Smartphones

• Tablets

• 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 20-volt, 5 amp protection." The LS05006VPQ33 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 don't meet the Type-C specification, and some adapters that only provide 20 V to Vbus can cause short circuits due to pin issues, twisting, or moisture. Without protection, downstream low-voltage circuits can be damaged.
