Can eFuse IC (electronic fusing) be used to protect USB VBUS from short circuits and IEC62368 Qualification?

Toshiba eFuse IC has acquired IEC62368-1 standard and is the most suitable product for protecting the short-circuit of the USB-terminal Vbus and power supply terminal.
Regarding the short-circuit protection, the short-circuit condition is detected at high speed, and the output current is quickly limited by controlling the internal MOSFET.
It also incorporates overvoltage protection and slew rate adjustment functions, allowing the functions of other power supply ICs to be integrated into the Toshiba eFuse IC.
Specific usage methods are as follows. TCKE8 series operates at voltages ranging from 4. 5V to 18V.
The overcurrent limit can be set to 0. 5A ~5A using an external resistor.
Please refer to the link application notes and datasheets below for further details.
