APX9322
Three-Phase Full-wave Sine-wave Brushless Motor Driver
Features
General Description
The APX9322 is a three-phase full-wave sine-wave
brushless motor drive by one-hall. 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 APX9322 is available
in QFN4x4-24A 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).
