General Description
The APX9267 is a single phase full wave motor driver for
DC fan motor, and speed 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 is built-in lock
protection. When fan is locked, the device will enter the
lockup protection mode. It is also with thermal shutdown
function. In normal operation, supply current is less than
5mA, but in PWM=0 standby mode, it is just around
150mA. Moreover, this feature will shutdown Amplifier
and FG. The APX9267 is available in MSOP-8 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).
