Functional Description DF319 is a controller which is target for 3-phase brushless DC motor with hall sensor; there are five functional modules inside the DF319: Main Control, Current Detector, Motor Sequence Control, Position Detector and Interface. Its functional descriptions are shown as below: 5.1. Main Control This Main Control module is coordinator to maintain the finite state of the system. It receives the command passed by user interface detector and motor current from current detector module, and then determines the next action for motor based on those two received conditions. 5.2. Current Detector This module is used to detect the feedback current of motor (ISENSE_IN) and send to main control module, the main control will stop the motor whenever the sensing current reaches the value corresponding to over current protection. 5.3. Motor Sequence Control The motor sequence control module controls the power MOSFET ON/OFF of motor. It depends on the position information sent by position detector module to output the six driving signals (PWM_AH, PWM_AL, PWM_BH, PWM_BL, PWM_CH, and PMW_CL) that can be directly associated to the sequence phase of motor.

Position Detector This module is used to detect the feedback hall signals of motor (HALL_A, HALL_B, and HALL_C) and send to motor sequence control module, the sequence control module will decide the next sequence phase to drive the motor. 5.5. Interface This module is used to detect the user interface, including PWM input and FG output. 6.
