Abstract
An isolated gate driver includes a first input terminal to receive gate information and one or more input terminals to receive configuration information. A modulation circuit generates a modulated signal having four possible states, each of the four possible states corresponding to a different unique pair of values of the gate information and the configuration information. The modulation circuit represents two of the states using on-off keying (OOK) while the configuration information is at a first value and represents two of the states as a modification to the OOK modulation based on the configuration information being at a second value. The modulated signal is sent over an isolation communication channel coupling a transmitter and receiver of the isolated gate driver.
