General Description
The APX9322 is a three-phase full-wave sine-wave
brushless motor drive by one-hall or sensor-less . This
IC built-in linear or direct PWM input speed control, lead-
ing angle setting, current limit and soft start features suit-
able for the three-phase brushless DC motors. The
APX9322 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).
