부하 제어 장치는, 부하를 구동하는 부하 제어 수단과, 전류 검출용 저항과, 차동 증폭기와, 전류 연산 수단을 구비한다. 부하 제어 수단은, 스위칭 소자의 한쪽을 ON으로 하고 스위칭 소자의 다른 쪽을 OFF로 하는 상태와, 스위칭 소자의 한쪽을 OFF로 하고 스위칭 소자의 다른 쪽을 ON으로 하는 상태를 반복하는 스탠바이 상태와, 스위칭 소자의 양쪽을 ON으로 하는 구동 상태를 전환 가능하다. 전류 연산 수단은, 구동 상태인 경우에 차동 증폭기로부터 출력된 값과 스탠바이 상태인 경우에 차동 증폭기로부터 출력된 오프셋값에 기초하여 전류 검출용 저항에 흐르는 전류를 연산한다.

    A load control device includes a load control means that drives a load, a current detection resistor, a differential amplifier and a current calculation means. The load control means can switch between a standby state a drive state, a state in which a first of the switching elements is turned ON and a second of the switching elements is turned OFF and a state in which the first of the switching elements is turned OFF and the second of the switching elements is turned ON being alternately repeated in the standby state, in which both of the switching elements are turned ON in the drive state. The current calculation means calculates a current that flows to the current detection resistor on the basis of a value output from the differential amplifier in the drive state and an offset value output from the differential amplifier in the standby state.
