There are two out- put drivers in APX9154 A 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. Output Switch Principle 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.

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.

A .2 - M ar., 2017 www .anpec.com .tw7 A P X 9 1 5 4 A 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 dut y 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. Fun ction De scription ( C on t.)

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. Bop Brp B=0 OUT1 OUT2 FG Start-up operation PWM Soft-Stwitch operation 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. 66.5m s (typ.) disableenable e nable PWM Lock protect enable (Internal) 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. Thermal Function
