Function Description
Lockup Protection and Automatic Restart
Output Switch Principle
The APX9154A built in a Hall-effect sensor plane to sense
the vertical magnetic flux density (B). There are two out-
put drivers in APX9154A to drive single-phase DC
brushless motor. When the N pole magnetic field close
to the IC marking surface and the magnetic flux density
higher than operate point (Bop), the OUT1 pin output will
turn to HIGH and the OUT2 pin output will turn to LOW.
When the N pole magnetic field far away the IC marking
surface and S pole magnetic field close to the IC marking
surface until the magnetic flux density higher than re-
lease point (Brp), the OUT1 pin output will turn LOW and
the OUT2 pin output will turn HIGH.
The APX9154A detects the rotation of the motor by inter-
nal hall sensor signal, and adjusts lock detection ON
time (TON) and lock detection OFF time (TOFF) by internal
counter.

Applying PWM pulses to the PWM pin directly, the duty
cycle of PWM pulses will control the output driver ON duty
directly. In PWM control, the high level of pulse signal
should be higher than 0.5*VDD and the low level should
be lower than 0.2*VDD. When the PWM pin is floating, the
output driver of APX9154A will be full duty to drive the
motor.

APX9154A
Function Description( Cont.)
Soft-Starf Function
The APX9154A provides the soft-start function to reduce
vibration at power-on and lock-restart moments. The soft-
start function has four stages 50% → 70% → 90% →
100%. At first the output duty is 50% after 64 FG H-L cycle
times the output duty is change to next stage 70% until
192 FG H-L cycle times the soft-start function will end. If
the voltage higher than 3.2V or Direct PWM Duty higher
than 50% soft-start function is enable,else the soft-start
function is disable.

Quick Start and StandbyMode
This IC would enter standby mode when the PWM input
keeps low level for then 66.5m(typ.). In standby mode, it
will shutdown amplifier and FG. In standby mode, the
lock protection function doesn’t work, therefore, starting
fan is unobstructed when releasing standby mode.

PWM Soft-Switch Function
66.5ms (typ.)
The APX9154A built in PWM soft-switch output control cir-
cuit to improve the vibration and noise of fan motor
operation. At start-up operation, the APX9154A drive the
output driver by square wave to force the fan motor start to
rotate. After several square wave outputs , the internal
PWM soft-switch control circuit will be enable to drive fan
motor to improve vibration and noise.

Thermal Function
The APX9154A is designed with a thermal protection to
protect the IC from the damage of over temperature.
Wheninternal junction temperature reaches 165oC, the
output devices will be switched off. When the IC’s junc-
tion temperature cools by 30oC, the thermal sensor will
turn the output devices on again resulting in a pulsed
Output during continuous thermal overload.
