5. TRAY MOTOR DRIVE CIRCUIT
1) Rotational Direction Control
- The forward and reverse rotational direction is controlled by FWD (pin
24) and REV (pin 25) inputs. Conditions are as follows.
- Vr(Power reference voltage) is (VM34-VBE) / 2
2) Motor Speed Control
- The motor speed is proportional to the differential voltage between the pin3(DO4+) and the pin2(DO4-).
- By applying the voltage to the pin23 of CTL, the motor speed can be controlled and it is linearly proportional to the
applied control voltage.
- When both VM3,4 and Vcc are 5V, and the applied control voltage is higher than 4V, the motor speed is not proportional
to the control voltage but the motor speed becomes constant.
- If the pin23 is opened, the motor torque becomes maximum.
- The maximum output swing is 3.8V, when VM3,4 and Vcc are 5V.
