Three-Phase Full-Wave Sensor-Less Drive Method
The APX9365D/E/F provides all the circuitry for sensor-
less speed control of three-phase brushless DC motor.
The controller functions include start-up circuit, back-EMF
commutation control, Pulse Width Modulation (PWM)
speed control, lock protection, and thermal shutdown
circuit.

Note: ANPEC lead-free products contain molding compounds/die attach materials and 100% matte tin plate termination finish; which
are fully compliant with RoHS. ANPEC lead-free products meet or exceed the lead-free requirements of IPC/JEDEC J-STD-020D for
MSL classification at lead-free peak reflow temperature. ANPEC defines “Green” to mean lead-free (RoHS compliant) and halogen
free (Br or Cl does not exceed 900ppm by weight in homogeneous material and total of Br and Cl does not exceed 1500ppm by
weight).
ANPEC reserves the right to make changes to improve reliability or manufacturability without notice, and
advise customers to obtain the latest version of relevant information to verify before placing orders.
