Integrated circuit for motor drive controller applications
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.
