Abstract: A circuit for controlling a first plurality of transistors connected in parallel and a second plurality of transistors connected in parallel, includes: a first plurality of stages, a respective one of the first plurality of stages being configured to supply a first control signal to a respective one of the first plurality of transistors; and a second plurality of stages, a respective one of the second plurality of stages being configured to supply a second control signal to a respective one of the second plurality of transistors. An output current of the respective one of the first plurality of stages is regulated based on a difference between a first value representative of a sum of output currents of each stage of the first plurality of stages and a second value representative of a sum of set points assigned to the first plurality of stages.

Abstract: An integrated circuit is configured for controlling automobile door lock motors. The circuit includes half-bridge driver circuits, with each half-bridge driver circuit having an output node configured to be coupled to a door lock motor. A control circuit is configured to control driver operation of the half-bridge driver circuits. A current regulator circuit senses current sourced by or sunk by at least one of the half-bridge circuits. The control circuit responds to the current regulator circuit and the sensed current by controlling the driver operation to provide for a regulated current to be sourced by or sunk by said half-bridge circuit. The control circuit further controls the half-bridge driver circuits to enter a tri-state mode in order to support the making of BEMF measurements on the motor.
