Three-Phase Full-Wave Sine-Wave Driver
The APX9322A is a three-phase full-wave sine-wave
brushless motor drive by sensor-less. This IC built-in
linear or direct PWM input speed control, leading angle
setting, current limit and soft start features suitable for
the three-phase brushless DC motors. The APX9322A is
available in QFN4x4-24 package (see Pin Configuration).

Note1: 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-020C 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 inhomogeneous material and total of Br and Cl does not exceed 1500ppm by
weight).
