Littelfuse Introduces New Electronic Fuse Protection IC for USB Type C Port Protection

Littelfuse Corporation (NASDAQ: LFUS), a company dedicated to powering a sustainable, connected and safer world. The company announced the launch of LS05006VPQ33, the newest member of its Electronic Fuse Protection IC product line, a multifunctional circuit protection device.

This new electronic fuse protection IC features an innovative design to protect USB Type C ports from short circuits, overvoltage and electrostatic discharge (ESD). The LS05006VPQ33 is a highly integrated protection IC for Type C PD Vbus with CC/SBU short circuits with 28 Vmax and 8 KV IEC -61000-4-2 ESD capability. 

The Electronic Fuse LS05006VPQ33 protection IC is ideally suited for use in a variety of USB Type C applications, including:

● Notebook computers

● Desktop computers

● Monitors

● Industrial computers

● Point-of-sale

● Smartphones

● Tablet PCs, and

● USB Type C PD Docking Station

"The LS05006VPQ33 is an expansion of Littelfuse's electronic fuse protection IC solution and is the Company's first electronic fuse to provide 20 V short circuit, overvoltage and system ESD protection for signal pins." Bernie Hsieh, APM of Littelfuse's Protection Semiconductors business, explains, "The LS05006VPQ33 offers increased reliability, longer life, lower maintenance costs and a compact product size. It can also be used with the LS2406ERQ23 electronic fuse for Vbus 20 volt, 5 amp protection."

The LS05006VPQ33 design addresses a critical issue in USB Type C controllers by protecting low-voltage silicon circuits from overvoltage, short-circuit and ESD shocks. Many USB Type C products do not comply with the Type C specification, and some are only available with 20 V to Vbus adapters, which can lead to short circuits due to pin problems, twisting or moisture. Without protection, downstream low voltage circuits may be damaged. The LS05006VPQ33 secures downstream low voltage circuits from overvoltage and IEC61000-4-2 ESD shocks.

In addition to higher reliability, longer life and lower maintenance costs, the LS05006VPQ33 offers other competitive advantages. It supports a higher Vmax value (28 V) with its 8 KV ESD contacts and a higher ESD rating in the SBU than other solutions on the market. These advantages make it a reliable and efficient USB Type C port protection solution that is an excellent choice for electronics engineers.
