Load drive control circuit

A load drive control circuit for controlling a load that includes a first terminal and a second terminal, the load drive control circuit comprising:

• a first bridge circuit connected between a power supply and ground, the first bridge circuit including a first power supply side transistor and a first ground side transistor, which are connected in series, and a first output terminal arranged between the first power supply side transistor and the first ground side transistor and connected to the first terminal of the load;
• a second bridge circuit connected between the power supply and the ground, the second bridge circuit including a second power supply side transistor and a second ground side transistor, which are connected in series, and a second output terminal arranged between the second power supply side transistor and the second ground side transistor and connected to the second terminal of the load;
• a detection circuit for detecting whether or not an unexpected current increase or voltage rise is occurring in at least one of the connection terminals of the load;
• and
• a control circuit for generating a control signal that deactivates the first power supply side transistor, first ground side transistor, second power supply side transistor, and second ground side transistor and electrically disconnects the load from the power supply when the detection circuit detects the occurrence of an unexpected current increase or voltage rise at the first terminal of the load during a period in which the load is in a suspended state.
