This IC has an internal counter to determine the shutdown time (TOFF) and restart time (TON). 66.5ms (typ.) Lock protect During shutdown time, the output drivers keep turn off for 5 seconds and then enter the restart time. During the enable (internal) restart time, one output is high and the other is low, which makes a torque for fan rotation. The restart time has 0.5 enable disable Figure 2. Quick Start Waveform second. If the locked condition is not removed, the shutdown/restart process will be recurred until the locked Variable Speed Control The APX9221 has a variable speed controller. The speed condition is released (see Fig1. Lockup/Auto Restart Waveform). is controlled by comparing the voltage of OSC, MIN and SET. The lowest speed drive duty is set by comparing the IN+ OSC oscillating voltage and MIN pin voltage when MIN pin voltage is lower than SET. When SET pin voltage is IN- OUT2 enable lower than MIN, PWM control system works by comparing the voltage of SET and OSC. When SET pin voltage is TOFF lower than OSC, upper and lower side's transistors are ON. When SET pin voltage is higher than OSC, upper TOFF side transistors are OFF and coil current re-circulates lower side transistor. The lower SET pin voltage is, the TON more output ON duty will be. Hence, the coil current will be enlarged and motor speed will be faster. Rotation OUT1 speed is able to feedback by FG output. The Output PWM frequency is fixed at 33 KHz. (See Figure 3. Rotation Waveform). FG Lock Lock Detection ReleaseReset IN+ IN- Figure 1. Lockup /Auto Restart Waveform SET MIN OSC Quick Start and Standby mode This IC would enter standby mode when the PWM input OUT1 OUT2 keeps low level for more than 66.5ms (typ.). In standby mode, it will shut down amplifier and FG. Thus, the sup- IL ply current is around 3.2mA. In standby mode, the lock protection function doesn’t work, therefore, starting fan is FG unobstructed when releasing standby mode. Full Speed Lowest Speed Figure 3.

However, hall signal the protection diode will cause a voltage drop on the supply voltage. The current rating of the diode must be larger Vhsy_ss OUT2 than the maximum output current. For the noise reduction purpose, there is a least 2.2µF capacitor (CIN) recommended connecting between VCC and GND (see Typical Application Circuit). OUT1 FG/RD Resistor The value of the FG/RD resistor could be decided by the Figure 7. When hall signal < Vhys_ss. IC does not operate properly. following equation: RFG = VCC − VFG IFG For example: VCC=24V, IFG =5mA, VFG=0.1V,RFG=4.78kΩ The value of resistor in the range of 1kΩ to 10kΩ is recommended. Adjustment of voltage between soft switches The width of soft switch before and after switching is controlled by SSW voltage.
