Abstract
A gate driver circuit may include a driving signal generating unit generating first and second control signals based on a data signal and a fault state signal and controlling gate detection, a driving inverter operating in response to the first and second control signals to generate a gate signal and providing the gate signal to a power switch element, and a soft turn-off/gate detecting unit operating in response to the second control signal, performing a soft turn-off in the case of a fault, and detecting the gate signal to provide a detected signal.
