Isolated gate driver for transmitting multiple information simultaneously
A recently granted patent (Publication Number: US11888658B2) discloses a method and apparatus for transmitting information across a single isolation communication channel. The method involves receiving first and second information and transmitting them simultaneously using a modulated signal across the communication channel. The modulated signal is generated based on the first and second information, with specific frequency deviations corresponding to changes in each type of information. Additionally, the method includes using on-off keying (OOK) modulation and frequency modulation to represent different states of the transmitted information.
Furthermore, the apparatus described in the patent includes input terminals for receiving gate and configuration information, a modulation circuit to generate a modulated signal based on this information, and a transmitter to send the modulated signal across the isolation communication channel. The modulation circuit is designed to create four distinct states in the modulated signal, each corresponding to a unique pair of values of the gate and configuration information. Frequency modulation is utilized to differentiate between these states, with varying frequencies indicating different combinations of the input information. The apparatus also includes components such as an oscillator and logic circuit to control the modulation process based on the input information, ensuring accurate transmission and reception of the data across the communication channel.
