Abstract:
A power control circuit according to one embodiment includes an H-bridge circuit formed using a plurality of power transistors. The power transistors are respectively connected to current measurement circuits that measure currents flowing through the power transistors. Each of the power transistors includes a main emitter and a sense emitter through which a current corresponding to a current flowing through the main emitter flows. Each of the current measurement circuits measures a current flowing through each of the power transistors by using a current flowing through the sense emitter included in the power transistor. A control circuit controls the power transistors based on current values respectively measured by the current measurement circuits.
