Functional Description DF329 is a controller which is target for 3-phase brushless DC motor with hall sensor; there are five functional modules inside the DF329: 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 mai ntain 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 c ontrol will stop the motor and set alarm output whenever the sensing current reaches the value corresponding to over current protection. 5.3. Voltage Detector This module is used to detect the feedback voltage of motor (UVOL_IN) and send to main control module, the main control will stop the motor and set alarm output whenever the sensing voltage reaches the value corresponding to under voltage over low protection. Motor Sequence PWM_AH PWM_BH PWM_CL ISENSE_IN Current Detector Main Control Interface PWM_IN FG/RD Position Detector HALL_A HALL_B HALL_C DF329 Voltage Detector UVOL_IN ALARM

Motor Sequence Control The m otor sequence control module controls the power MOSFET ON/OFF of motor. It depends on the position information sent by position d etector module to output the six driving signals (PWM_AH, PWM_AL, PWM_BH, PWM_BL, P WM_CH, and PMW_CL) that can be directly associated to the sequence phase of motor. 5.5. 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. 5.6. Interface This module is used to detect the user interface, including PWM input, FG output and ALARM output. 6.

POR for DC Fan Application As shown in Fig 8-1, DF329 generates a good power on reset (POR) signal when VDD rises from 0V to 5V in If there are a lot of abnormal power noises in VDD power-on time period and TPOR and TFSV do not meet the specifications, DF329 is not able to guarantee circuit initialization and may cause a malfunction. VDD VDD Power-on Time 0.7V 1.6V TFSV TPOR TFSV < 10ms TPOR < 50ms time Fig. 8-1 During power-off as shown in Fig 8-2 and Fig 8-3, VDD has to be discharged to VPDRV (max. is 0.7V) for the next power-on. In case VDD is more than VPDRV, it is not recognized to do the next power-on. VDD Power-off Max. is 0.7V time VDD VPDRV VDD Power-off Max. is 0.7V time VDD VPDRV Fig. 8-2 Fig. 8-3 NOTICE: It may cause DF329 malfunction, fail or crash when power-on and power-off do not meet the specifications. Another proper POR is needed in order to get rid of such status.
