APX9151S
Function Description
Output Switch Principle
The APX9151S built in a Hall-effect sensor plane to sense
the vertical magnetic flux density (B). There are two out-
put drivers in APX9151S 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 LOW and the OUT2 pin output will turn to HIGH.
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 HIGH and
the OUT2 pin output will turn LOW.

Speed Control by Direct PWM Input Signal
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 x VDD and the low level should
be lower than 0.2 x VDD. When the PWM pin is floating, the
output driver of APX9151S will be full duty to drive the
motor.

Lockup Protection and Automatic Restart
The APX9151S 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 inter-
nal counter.

Function Description ( Cont.)
PWM Soft-Switch Function
Green Motor Drive (GMD)
The APX9151S built in PWM soft-switch output control
circuit to improve the vibration and noise of fan motor
operation. At start-up operation, If the voltage higher than
3.8V or PWM mode, the APX9151S drive the output driver
by 50% duty square wave to force the fan motor start to
rotate. After several 50% duty square wave outputs, the
internal PWM soft-switch control circuit will be enable to
drive fan motor to improve vibration and noise.
The APX9151S is a GMD driver IC for high efficiency fan
motor. Put the sensor at center of two slots, the motor will
automatically work in higher efficiency condition.

Quick Start and Standby Mode
This IC would enter standby mode when the PWM input
keeps low level for then 66.5ms(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.
