To provide a general load drive circuit which can be corresponded to various kinds of electric loads.SOLUTION: A load drive circuit (1) is structured so as to control a driving of an electric load (3) as a DC load. The load drive circuit comprises: a control unit (12) generating and outputting a control signal for controlling a flow state of a load current flowing in the electric load; a switching element (111) for switching and controlling the flow state of the load current on the basis of the control signal; and a current detection unit (112) detecting the load current. The control unit comprises: a type determination unit (122) determining a type of the electric load on the basis of the load current detected by the current detection unit; and a control signal output unit (125) generating and outputting the control signal on the basis of the type determined by the type determination unit.SELECTED DRAWING: Figure 1

    【課題】多種多様な電気負荷に対応させることが可能な、汎用的な負荷駆動回路を提供すること。【解決手段】負荷駆動回路(1)は、直流負荷である電気負荷(3)の駆動を制御するように構成されている。この負荷駆動回路は、前記電気負荷に通流する負荷電流の通流状態を制御するための制御信号を生成し出力する制御部(12)と、前記制御信号に基づいて前記負荷電流の通流と遮断とを切換制御するスイッチング素子(111)と、前記負荷電流を検出する電流検出部(112)とを備える。前記制御部は、前記電流検出部によって検出された前記負荷電流に基づいて前記電気負荷の種別を判定する種別判定部(122)と、前記種別判定部によって判定された前記種別に基づいて前記制御信号を生成し出力する制御信号出力部(125)とを備える。【選択図】図1
