MCF8315C-Q1: Need a bldc device controls the speed directly via LIN communication

Part Number: MCF8315C-Q1
Other Parts Discussed in Thread: MCT8315A

Is there a device that can directly control the amount of BLDC's 3-phase motor current? The primary chip is not required to process current, and the primary chip controls the speed directly via LIN communication.

    Our MCx devices offer a torque/power loop control mode. In this control mode the phase current to the motor is regulated to be a set value. Please see section 6.3.12.4 of the MCF8315C-Q1 datasheet for a description of torque mode and section 7.3.13 of the MCT8315A datasheet for a description of the power loop control mode.

    Could you provide a simple block diagram just so that I can make sure I understand the intended connections? 

    Regards,
