Provided are an open-mode protection device and an electronic device having the same. An open-mode protection device according to an embodiment of the present invention is connected in parallel to each of a constant current source and a load configured with a light emitting diode (LED). The open-mode protection device comprises a first external electrode connected to one sides of the constant current source and the load; a second external electrode connected to the other sides of the constant current source and the load, and a ground; a protection unit configured to bypass, to the ground through the second external electrode, an overvoltage or an overcurrent flowing into the first external electrode; and a current suppressing unit connected in series to the protection unit and configured to sense a temperature or current of the protection unit and reduce the current of the protection unit as the temperature or current increases.
