CPC H02H 7/20 (2013.01) | 15 Claims |
1. An electronic device, comprising:
a first group III nitride transistor; and
an over current protection (OCP) circuit comprising:
an input device configured to receive a control signal and to generate a first voltage to a gate of the first group III nitride transistor; and
a detection device configured to generate an output signal having a first logical value if a current at a drain of the first group III nitride transistor is less than a predetermined value and to generate the output signal having a second logical value if the current at the drain of the first group III nitride transistor is equal to or greater than the predetermined value, wherein the first logical value is different from the second logical value; and wherein the detection device includes:
a comparator having a first input configured to receive a reference voltage, a second input configured to receive a second voltage and an output configured to output a third voltage; and
a first inverter having an input configured to receive the third voltage and an output configured to output the output signal.
