Abstract
A electronic device includes a transceiver including a transmitter and a receiver that operate based on a power source voltage and a pad voltage applied from a pad; and an overvoltage protection circuit to apply a first protection voltage to the transmitter and a second protection voltage to the receiver. The overvoltage protection circuit includes: a reference voltage generator to generate a reference voltage when the power source voltage is in an on state; and a voltage detector to set the first protection voltage and the second protection voltage based on the reference voltage when the power source voltage is in an on state, and set the first protection voltage and the second protection voltage based on the pad voltage when the power source voltage is in an off state.
