E-Fuse & Load Switches

Safety for Outgoing Connections

If a PCB being actively supplied with current is connected to another electrical circuit, there is a risk of overvoltages occurring during the charge balancing. This can be prevented by what are known as E-fuse modules, which delimit voltages and currents in the hot-swap mode. Load switches limit the emitted current to a preset value.

This then, for instance, prevents an unknown USB device drawing more than the permitted amount of current from a host. The use of these modules increases system safety whenever several active systems are connected to one another.
