SLVSIM2A June 2025 – August 2025 TPD4S480-Q1
PRODUCTION DATA
The TPD4S480-Q1 is a single chip USB Type-C port protector that provides 48V short-to-VBUS overvoltage and ESD protection. The VBUS pins short to the CC and SBU pins inside the USB Type-C connector due to the small pin pitch of the USB Type-C connector and non-compliant USB Type-C cables and accessories. Because of this short-to-VBUS event, the CC and SBU pins need to be 48V tolerant, to support protection on the full USB PD-EPR voltage range. The TPD4S480-Q1 integrates four channels of 48V short-to-VBUS overvoltage protection for the CC1, CC2, SBU1, and SBU2 pins of the USB Type-C connector.
Additionally, IEC 61000-4-2 system level ESD protection is required to protect a USB Type-C port from ESD strikes generated by end product users. The TPD4S480-Q1 integrates four channels of IEC61000-4-2 ESD protection for the CC1, CC2, SBU1, and SBU2 pins of the USB Type-C connector, all of the low-speed pins on the USB Type-C connector. Additionally, high-voltage ESD protection that is 55V DC tolerant is required for the CC and SBU lines to simultaneously support ESD and short-to-VBUS protection. The TPD4S480-Q1 integrates a high-voltage ESD diode designed to work in conjunction with the overvoltage protection FETs inside the device.
