To provide a wiper drive circuit of a simple circuit configuration which can be applied to a redundant system of a two-battery configuration.SOLUTION: When a power source failure does not occur, power supply to a Lo terminal 111a is performed by a first battery BATT1, and power supply to a Hi terminal 111b is performed by a second battery BATT2. When a power failure occurs in any one of the first battery BATT1 and the second battery BATT2, power supply to a wiper motor 111 is performed by the other in which a power failure does not occur.SELECTED DRAWING: Figure 1

    【課題】2バッテリ構成の冗長システムに適用できる簡素な回路構成のワイパ駆動回路を提供する。【解決手段】電源失陥が発生していないときには、Lo端子111aへの電力供給が第1バッテリBATT1で行われ、Hi端子111bへの電力供給が第2バッテリBATT2で行われるようにする。そして、第1バッテリBATT1と第2バッテリBATT2のうちのいずれか一方に電源失陥が発生したときには、電源失陥していない他方によってワイパモータ111への電力供給が行われるようにする。【選択図】図1
