could reduce the peak cur-rent at power on and lock mode. The PWM control sys-tem
works depending on the comparison among the volt-age of
SET, MIN, and OSC. The device
is equipped witha built-in lock protection, which protects the fan when it islocked.

Function Description
Variable Speed Control
The APX9211 has a variable speed controller. The speedis controlled by comparing the
voltage of OSC, MIN andSET. The lowest speed drive duty is set by comparing theOSC
oscillating voltage and MIN pin voltage when MINpin voltage is lower than SET. When
SET pin voltage islower than MIN, PWM control system works by compar-ing the voltage
of
SET
and
OSC.

transistors are OFF and coil current re-circulateslower side transistor. The lower

SET pin voltage is, themore output ON duty will be. Hence, the coil current willbe
enlarged and motor speed will be faster. Rotationspeed is able to feedback by FG output.
PWM basic fre-quency will be 30 KHz when putting on COSC=220pF (See Figure 1. Rotation
Waveform).
CT
During the discharging interval, the output drivers areswitched off until the CT
voltage is discharged to 1V by a0.2?A sink current, and the circuit will switch the
capacitorto charge. In the charging interval, the IC enters the re-start time; one
output is high and another is low, whichmakes a torque for fan rotation until the
CT voltage ischarged to 3V by a 2?A source current. If the locked con-dition still

Soft-Start Function
IL
FG
The APX9211 provides the soft-start function to avoid peakcurrent at power-on and
lock-restart moments. Connect-ing the capacitor from S-S pin to 5VREG can
determinethe soft start time. The soft-start function works depend-ing on the
comparison between the voltages of S-S, SET,MIN and OSC.An internal constant sink

Lockup Protection and Automatic Restart
The APX9211 provides the lockup protection and auto-matic restart functions to
prevent the coil burnout whilethe fan is locked. Connecting the capacitor from CT
pin toGND determines the shutdown time and restart time. Asthe fan is locked, the
charge/discharge circuit will chargethe CT capacitor to 3V by a 2?A source current
for a lockeddetection time, and then the circuit will switch the capaci-tor to
discharge.

The APX9211 is designed with a thermal protection toprotect the IC from the damage
