Littelfuse, Inc. USB Type-C Port CC/SBU Short-to-VBUS Overvoltage Protection LS05006VPQ33

The LS05006VPQ33 is a protection device that helps prevent 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 LS05006VPQ33, downstream low voltage circuits are safeguarded against overvoltage and IEC61000-4-2 ESD strike. 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 pulldown resistor to take over without causing confusion for the power source. Automatically process signals and work transparently without interference or burden on Type-C controller operation. Overvoltage protection for 4-channels (CCxI, SBUxI) with 24 V tolerant switch and IEC 61000-4-2 ESD protection Up to 600 mA high current capability for CC1/CC2 overvoltage protection FETs to pass VCONN power. Include integrated CC1/CC2 pull-down resistors to handle mobile devices dead battery conditions. Designed in a compact package QFN3x3_20L
