1. An electrical device, comprising:
an input voltage node configured to receive a first voltage signal from an energy source;
an input reference node configured to receive a reference signal from the energy source;
a first switch coupled between the input voltage node and an output voltage node;
a second switch coupled between the input reference node and an output reference node; and
a current sensor circuit coupled to the output voltage node and coupled respectively to the first switch and the second switch, the current sensor circuit configured to open the first and second switches in response to sensing a magnetic field caused by a current signal at the output voltage node that exceeds a threshold current, the opening within six microseconds of the sensing.
