Semiconductor device

A semiconductor device for operating a load, comprising:

• a semiconductor chip, including
• an output element that receives a drive signal, to thereby perform switching to operate the load, the output element having a gate and an emitter,
• a current monitor element that monitors a current flowing through the output element, the current monitor element having a gate and a sense emitter, and
• a temperature detection element that detects a temperature of the output element, the temperature detection element having an anode and a cathode,
• the semiconductor chip further having:
• a first electrode pad connected to the gate of the output element and the gate of the current monitor element,
• a second electrode pad connected to the sense emitter of the current monitor element and to the anode of the temperature detection element via a current limiting element, and
• a third electrode pad connected to the cathode of the temperature detection element, which is grounded without being connected to the emitter of the output element;
• and
• a control circuit connected to the first electrode pad and the second electrode pad, the control circuit being configured to
• input the drive signal to the gate of the output element via the first electrode pad,
• operate in a temperature detection mode in response to the output element being turned off, the temperature detection mode being a mode in which the control circuit
• receives a temperature detection voltage output from the temperature detection element via the second electrode pad, and
• detects a temperature state of the output element, and
• operate in a current detection mode in response to the output element being turned on, the current detection mode being a mode in which the control circuit
• receives a sense current output from the current monitor element via the second electrode pad, and
• detects a current state of the output element.
