Abstract

Techniques for driving a plurality of inductive actuators are described herein. According to these techniques, a driver unit includes a clock terminal that receives an external clock signal used by an external control unit. The driver unit further includes a serial bus interface configured to communicate with the external control unit via a serial bus. The serial bus is configured to communicate both of trigger commands synchronized to the external clock signal that indicate to at least one of a plurality of programmable control circuits (PCUs) to generate drive signals in response to the trigger commands that are synchronized with the external clock signal and data associated with at least one of the plurality of PCUs and synchronized with the external clock signal, wherein the data is used by the at least one of the plurality of PCUs to generate the drive signals in response to the trigger commands.
