There are two output drivers in APX9172/72A/72B to drive singlephase DC brushless motor. For example of TSOT/23-6 package, when the N pole magnetic field close to the IC TOFF OUT2 marking surface and the magnetic flux density higher than operate point (Bop), the OUT1 pin output will turn to LOW TOFF TON and the OUT2 pin output will turn to HIGH. When the N pole magnetic field far away the IC marking surface and OUT1 S pole magnetic field close to the IC marking surface until the magnetic flux density higher than release point FG (Brp), the OUT1 pin output will turn HIGH and the OUT2 pin output will turn LOW. Bop Brp N RD S Marking Surface S Marking Surface N (SOP-8F) S Release Reset Lock Lock Detection (SOP-8F) N Marking Surface N Marking Surface S (TSOT-23-6) 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 (TSOT-23-6) VOUT1 VOUT1 directly. In PWM control, the high level of pulse signal should be higher than 2.5V and the low level should be B Brp Bop lower than 0.8V. When the PWM pin is floating, the output driver of APX9172/72A/72B will be full duty to drive the B Brp Bop Bhys Bhys VOUT2 VOUT2 motor. Quick Start and Standby Mode This IC would enter standby mode when the PWM input B Brp Bop B Brp keeps low level for then 66.5m(typ.). In standby mode, it will shutdown amplifier and FG. In standby mode, the Bop lock protection function doesn’t work, therefore, starting fan is unobstructed when releasing standby mode. Lockup Protection and Automatic Restart The APX9172/72A/72B detects the rotation of the motor by internal hall sensor signal, and adjusts lock detection ON time (TON) and lock detection OFF time (TOFF) by inter- PWM nal counter. 66.5ms (typ.)
