APX9365A/B/C
Three-Phase Sensor-Less Fan Motor Driver
Features
General Description
• Three-Phase Full-Wave Sensor-Less Drive Method
• Adjustable Forced Commutation Frequency
(for Start-up)
• Built-In External PWM Speed Control
• Built-In Quick Start Function
• FG (Rotation Speed Detection) Output (for
APX9365A)
RD (Lock Detection) Output (for APX9365B)
1/2FG (Rotation Speed Detection) Output (for
APX9365C)
• Soft Switching Circuit (for Noise Reducing)
• Power Saving Function (PWM Duty Input is 0%)
• Built-In Lock Protection and Auto Restart Function
• Thermal Shutdown Circuit
• Lead Free and Green Devices Available
(RoHS Compliant)
Applications
• Motor Driver For Silent Fan Motors
The APX9365A/B/C 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.
The APX9365A/B/C is suitable for both game machine
and CPU cooler that need silent drivers. It is available in
VTDFN3x3-10 package.

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.
