11 / 16 page Data Sheet 11 Jun. 2008 Rev. 2. 2 BCD Semiconductor Manufacturing Limited SINGLE PHASE FULL WAVE DIRECT PWM MOTOR DRIVER AM4961 Operating Diagram Note 6: 1. Low Speed Setting Mode When VPWM voltage is higher than VMIN pin voltage, motor speed is settable by VMIN pin voltage. The mini- mum drive duty cycle is settable by comparing COSC oscillating voltage and VMIN pin voltage. VPWM voltage is decided by variation of PWM duty. 2. Variable Speed Setting Mode When VPWM voltage is lower than VMIN pin voltage, PWM control system works by comparing VPWM voltage and COSC voltage. If VPWM voltage is higher, the ON duty cycle of the upper side transistors will be minimized and motor speed becomes lower. Vice versa. 3. Full Speed Rotation Mode At a certain PWN duty, when VPWM voltage is lower than the low side of COSC output voltage, the motor will run at full speed. Figure 10.
