General Description
The APX9149A is an integrated Hall Effect Sensor IC designed for electric commutation of two-phase DC brushless motor applications. In DC fan applications, the APX9149A provides lower driving current under 7.5V (typ.) VDD supply voltage for low noise applications. The device is built-in lock protection. When the fan is locked, the device will enter the lock protection mode. The APX9149A is available in a low cost TO-92M4 package.
