General Description
   The APX9275A is a single phase full wave motor driver for DC fan motors, and can apply to three type speed control methods. The output signals of this IC are the amplifications of hall input signals. It is suitable for both game machine and CPU cooler that need silent fans. 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, the supply current is less than 8mA. The APX9275A is available in MSOP-10 and SOP-10 packages.
