Type-C VBUS eFuse
These Type-C VBUS eFuses are 3A low-loss single-channel power switches with a high output absolute rating of 28V to protect USB Type-C ports against abnormal voltage and current conditions. Their current limit is programmable by an external resistor to protect the power source from overcurrent or short-circuit conditions.
