Classification: H03K

Abstract:
A gate driver comprising:an edge detection circuit for detecting leading and trailing edges of a control input signal; an ON pulse generation circuit for generating an ON pulse in response to the leading or trailing edge of the control input signal, which is detected by the edge detection circuit; a first OFF pulse generation circuit for generating a first OFF pulse in response to the leading or trailing edge of the control input signal, which is detected by the edge detection circuit; a status hold circuit for driving an output element in response to the ON pulse outputted from the ON pulse generation circuit and for holding driving status of the output element until the first OFF pulse is outputted from the first OFF pulse generation circuit; and a second OFF pulse generation circuit for generating a second OFF pulse in response to a protect operation signal and for supplying the second OFF pulse to the status hold circuit, thereby to stop driving of the output element when protect operation is instructed by the protect operation signal.
