Drive circuit, drive method, and semiconductor system

A drive circuit of a semiconductor device comprising:

• a control section configured to output (i) a control signal in accordance with an input signal and (ii) a release signal when an error detection signal is input thereto;
• a first level shift section configured to raise a level of the control signal and a level of the release signal input from the control section;
• a high side drive section configured to control the semiconductor device based on the control signal of which the level has been raised by the first level shift section;
• and
• a second level shift section configured to lower a level of a signal from the high side drive section for input to the control section, wherein
• the high side drive section has an error detection section configured to output the error detection signal when the semiconductor device is in an error status, and maintain the output of the error detection signal until the release signal of which the level has been raised by the first level shift section is input,
• the control section has:
• a control signal generation section configured to generate the control signal in accordance with the input signal;
• an error handling section configured to generate the release signal when the error detection signal is input via the second level shift section;
• and
• a first selection section configured to receive the control signal from the control signal generation section and the release signal from the error handling section, select either the control signal or the release signal, and output the selected signal to the first level shift section, and
• the error detection section stops the output of the error detection signal when the release signal of which the level has been raised by the first level shift section is input.
