The APX9266 is a single-phase full-wave motor driver for

DC fan motor, and its speed can be controlled by PWM

input signal. The output signal of this IC is the amplified

hall input signal. It is suitable for both game machine and

CPU cooler that need silent drivers. The device has lock

protection function and the lock-restart timing can be

tunable by CT capacitor. The device is also with thermal

shutdown function. In normal operation, the supply cur-

rent is less than 3mA, but in PWM=0 standby mode, it is

just around 130

µA. Moreover, this feature will shut-

down HB, Amplifier, and FG. The APX9266 is available

in MSOP-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-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).
