General Description
The APX9270 is a single phase, DC brushless motor
driver with PWM variable speed control and current limit
features suitable for the fan of personal computer’ power
s
supply and CPU cooler. The PWM control system includes
thermistor input signal and direct PWM input signal, en-
abling highly silent and low vibration speed control. The
device is equipped with a built-in lock protection, which
protects the fan when it is locked. It also has rotation
speed detection output and thermal protection function.
The APX9270 is available in SSOP-20 and TSSOP-20P
packages (see Pin Configurations).

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-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 in homogeneous material and total of Br and Cl does not exceed 1500ppm by
weight).
