ELECTRONIC DEVICE FOR OVERVOLTAGE PROTECTION - A simplified explanation of the abstract
This abstract first appeared for US patent application 18349823 titled 'ELECTRONIC DEVICE FOR OVERVOLTAGE PROTECTION
Simplified Explanation
The abstract describes an electronic device with an overvoltage protection circuit that applies different protection voltages to the transmitter and receiver based on the power source voltage and pad voltage.
- Transceiver includes a transmitter and receiver operating based on power source voltage and pad voltage.
- Overvoltage protection circuit applies first protection voltage to transmitter and second protection voltage to receiver.
- Reference voltage generator generates reference voltage when power source voltage is on.
- Voltage detector sets protection voltages based on reference voltage when power source voltage is on, and based on pad voltage when power source voltage is off.

Original Abstract Submitted
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.
