Abstract
A semiconductor unit includes a semiconductor device, a controller, and a resistor. The semiconductor device includes a transistor arranged between a positive electrode of a battery and an inverter circuit electrically connected to the battery. The controller is connected to a control terminal of the transistor and configured to control the transistor. The resistor arranged between the control terminal and the controller. The controller controls the transistor so that when a current flowing to the transistor is greater than or equal to a threshold value, the transistor is deactivated. The resistor has a resistance value that is greater than or equal to 100 Ω.
