Abstract: A system comprises a gate driver that is configured to couple to a transistor disposed in a transistor module via a first pin. The gate driver comprises a duty cycle measurement circuit having a first input terminal and a first output terminal, the first input terminal coupled to a second pin via an isolator. The duty cycle measurement circuit comprises a flip-flop, a counter, a shift register, and a comparator. The system comprises an analog to digital converter circuit having a second input terminal, a second output terminal, and a reference terminal, the second input terminal coupled to a third pin configured to couple to a temperature-sensitive device disposed in the transistor module, the second output terminal coupled to a fourth pin via the isolator, and the reference terminal coupled to the first output terminal.
