High Sensit iv it y Hall I C for FAN Dr iver

The APX9149 is an integrated Hall Effect Sensor IC de-

signed for electric commutation of two-phase DC

brushless motor applications. In DC fan applications,

the APX9149 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

APX9149 is available in a low cost TO-92M4 package.
