The TPD4S480-Q1, TPD4S481-Q1, and TPD4S201-Q1 are a series of 4-channel ESD and OVP protection devices for USB Type-C Power Delivery applications. Each device provides 8kV contact and 15kV air-gap IEC61000-4-2 ESD protection. The TPD4S480-Q1 and TPD4S481-Q1 protect against short-to-VBUS events up to 48V for USB PD EPR systems. TPD4S201-Q1 supports short-to-VBUS events up to 20V for USB PD SPR systems.
TPD4S480-Q1 integrates a VBUS divider circuit and FET driver, allowing PD controllers not rated for EPR operation to safely operate in EPR voltage ranges. When enabled by GPIO or automatically when VBUS exceeds 24V, the TPD4S480-Q1 disables the optional external blocking FET and enables the voltage divider. This action protects 20V rated PD controllers and allows the use of existing VBUS sense circuits.
