Overview
The TPD6S300ARUKR is a single-chip USB Type-C port protection solution developed by Texas Instruments. This device is designed to provide comprehensive protection against overvoltage and electrostatic discharge (ESD) for USB Type-C ports. It addresses the specific challenges posed by the close proximity of pins in the USB Type-C connector, which can lead to short circuits and exposure to high voltages. The TPD6S300ARUKR ensures that the CC and SBU pins are tolerant to 20-V conditions, even though they operate at 5 V or lower, thereby safeguarding the system from potential damage.
