A main controller is coupled with a first cluster coupled with a second cluster in a daisy chain. The main controller is configured to determine a measured delay time associated with a first cluster coupled with a second cluster in a daisy chain topology, and determine a propagation delay associated with the first cluster based on the measured delay time. The main controller is further configured to generate a message to the second cluster which includes a command to be executed by the second cluster, and send the message, through an isolated interface of the main controller, to the second cluster based on the determined propagation delay to execute the command to actuate the second cluster synchronized to a switching clock of the main controller.

Propagation delay compensation in daisy-chain topologies

Disclosed is an electronic drive circuit and a drive method. The drive circuit includes an output; a first output transistor comprising a control node and a load path, wherein the load path is coupled between the output and a first supply node; a voltage regulator configured to control a voltage across the load path of the first output transistor; and a first driver configured to drive the first output transistor based on a first control signal.
