Combination oil control valve and fuel injector driver

An engine control method, comprising:

• by a first high side switch, selectively connecting and disconnecting a first reference potential to and from a first node, respectively,
• the first node configured to be electrically connected to:
• a second node and a first end of a first inductor coil of a fuel injector of a cylinder;
• and
• a first end of a second inductor coil of an oil control valve of the cylinder;
• by a second high side switch, selectively connecting and disconnecting a second reference potential to and from the second node, respectively;
• by a first low side switch, selectively connecting and disconnecting a ground reference potential to and from a second end of the second inductor coil of the oil control valve of the cylinder, respectively;
• and
• by a second low side switch, selectively connecting and disconnecting the ground reference potential to and from a second end of the first inductor coil of the fuel injector of the cylinder, respectively.
