Abstract
A surge protection apparatus includes a signal determination unit configured to generate a control signal by detecting a surge on a power line, and a switching unit connected between the power line and a ground terminal and configured to include a power transistor that is turned on in response to the control signal.
Claims20
A surge protection apparatus comprising:
- a signal determination unit configured to generate a control signal by detecting a surge on a power line;
- and
- a switching unit connected between the power line and a ground terminal and configured to comprise a power transistor that is turned on in response to the control signal.
A surge protection apparatus comprising:
- a switching unit connected between a first power line and a ground terminal;
- and
- a signal determination unit connected between the first power line and a first terminal, and configured to generate a control signal by detecting a surge on the first power line,
- wherein the switching unit comprises a power transistor for connecting a first node to the first terminal in response to the control signal so as to electrically connect the first power line to the ground terminal, and
- wherein the first terminal is a terminal for detecting a fault in or damage to the power transistor.
