LS05006VPQ33 Overvoltage Protection Device

Littelfuse's LS05006VPQ33 protection device prevents damage to electronic products with USB Type-C ports. It protects against short-circuits, overvoltage up to 24 V, and electrostatic discharge (ESD). 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, low-voltage silicon circuits in Type-C controllers can be damaged. With the LS05006VPQ33, downstream low-voltage circuits are safeguarded against overvoltage and IEC61000-4-2 ESD strikes.

The LS05006VPQ33 has a CC pin pull-down resistor that helps power up and charge mobile devices with dead batteries. Once the system power is up, the device automatically cuts out the CC pin pull-down resistor, allowing the Type-C controller’s CC pin pull-down resistor to take over without causing confusion for the power source.
