TPS272C45: Difference between high side switch and efuse

Hi Naizeng,

I recommend reading through this white paper: https://www.ti.com/lit/eb/slyy168/slyy168.pdf 

The major difference is that eFuses are made for input power protection while high side switches are meant to drive downstream loads. The protection features integrated in these devices are selected for these applications.

Thanks,
