Drive circuit, electronic apparatus, and method of controlling drive circuit

An electronic apparatus, comprising:

• a capacitive load;
• a positive-side circuit configured to:
• control current supplied from a power source to a node to flow to a positive-side terminal of the capacitive load in a first drive mode, and
• control current from the positive-side terminal of the capacitive load to flow to the node in a second drive mode;
• and
• a negative-side circuit configured to:
• control current from a negative-side terminal of the capacitive load to flow to the node in the first drive mode, and
• control the current supplied from the power source to the node to flow to the negative-side terminal in the second drive mode,
• wherein current flow between the capacitive load and the node is bidirectional.

A method of controlling a drive circuit, the method comprising:

• controlling, by a positive-side circuit, current supplied from a power source to a node to flow to a positive-side terminal of a capacitive load in a first drive mode;
• controlling, by the positive-side circuit, current from the positive-side terminal of the capacitive load to flow to the node in a second drive mode;
• controlling, by a negative-side circuit, current from a negative-side terminal of the capacitive load to flow to the node in the first drive model;
• and
• controlling, by the negative-side circuit, current supplied from the power source to the node to flow to the negative-side terminal in the second drive mode, wherein current flow between the capacitive load and the node is bidirectional.
