Output Switch Principle
The APX9149A builts in a Hall-effect sensor plane to
sense the vertical magnetic flux density (B). There are
two output drivers in APX9149A to drive two-phase DC
brushless motor. When the South pole magnetic field is
close to the IC marking surface and the magnetic flux
density higher than operate point (Bop), the DO pin out-
put will turn ON and the DOB pin output will turn OFF.
When the South pole magnetic field far away the IC mark-
ing surface and North pole magnetic field close to the IC
marking surface until the magnetic flux density higher
than release point (Brp), the DO pin output will turn OFF
and the DOB pin output will turn ON.

Lockup Protection and Automatic Restart
The APX9149A detects the rotation of the motor by inter-
nal hall sensor signal, and adjusts lock detection ON
time (T
ON) and lock detection OFF time (TOFF) by internal
counter.
Thermal Protection
The APX9149A has a thermal protection. When the inter-
nal junction temperature reaches 165oC, the output de-
vices will be switched off. When the IC’s junction tem-
perature cools by 30oC, the thermal sensor will turn the
output devices on again, resulting in a pulsed output dur-
ing continuous thermal protection.
Voltage Speed Control Function
In some DC fan applications, the system adjusts the in-
put power voltage to control fan speed. The APX9149A
internal circuit controls the lower fan speed in the low
voltage region between VTH2 and VTH1. When adjusts
the VDD pin voltage from 12V to VTH1 (7.5V typical), the
APX9149A will apply lower current to coils and the fan
speed will be lower than original fan. A slower fan speed
will have a smaller fan noise.
