Semiconductor device

A semiconductor device comprising:

• an output transistor coupled between a first terminal and a second terminal;
• a first overcurrent detection unit configured to detect whether a drain-source voltage of the output transistor is greater than or equal to a first reference value and to output a first detection signal;
• a second overcurrent detection unit configured to detect whether an output current is a second reference value, the output current being a current passing through the output transistor, and to output a second detection signal;
• a latch circuit configured to, when receiving the first detection signal indicating that the drain-source voltage is greater than or equal to the first reference value, latch the second detection signal;
• and
• a drive circuit configured to, based on an output of the latch circuit, control the output transistor to turn off the output transistor,
• wherein, when the latch circuit receives the first detection signal indicating that the drain-source voltage is smaller than the first reference value, the latch circuit outputs the second detection signal without latching the second detection signal, and based on the output of the latch circuit, the drive circuit controls the output transistor to turn on or off the output transistor.
