• Manufacturer Part Number: FAN8034
• Description: 6-CH Motor Driver
• Manufacturer: Fairchild Semiconductor

6. Tray, Changer,panel Motor Drive Part
• Rotational direction control
• Where Vp(Power reference voltage) is approximately about 3.75V at PVCC2=8V ) according to equation (1).
• Where out1 pins are pins24 and out2 pins are pins25
• Motor speed control (When SVCC=PVCC2=8V)
The forward and reverse rotational direction is controlled by FWD (pin16) and REV (pin17) and the input conditions are as
follows.
- The almost maximum torque is obtained when the pin (15(CTL1, 2, 3)) is open.
- If the voltage of the pins (15 (CTL)) is 0V, the motor will not operate.
- When the control voltage of the pin15 is between 0 and 3.25V, the differential output voltage(V(out1,out2)) is about two
- When the control voltage is greater than 3.25V, the output voltage is saturated at the 6.5V because of the output swing
times of control voltage. Hence, the control to the differential output gain is two.
