Abstract
To achieve, in a load drive device including an H-bridge circuit, miniaturization of a capacitor or/and the constituent elements of the H-bridge circuit (e.g., reduction in volume) with circuit elements, for example, switching elements included in the H-bridge circuit, being inhibited from breaking down or destroying even in a case where a load is overloaded. The invention is disclosed in which, as a solution to the achievement, first and second modes are provided as a switching mode for the switching elements 11, 12, 13, and 14 and switching is appropriately performed between the first and second modes.
