6. TRAY, CHANGE MOTOR DRIVE PART
• Rotational direction control
• where Vr is (Vcc - Vbe) / 2 = 3.65V (at Vcc=8V)
• where Out1 pins are pins 24 and 26, and out2 pins aer pins 25 and 27
• Motor speed control
The forward and reverse rotational direction is controlled by FWD (pin 13, 16) and REV (pin 14, 17) input conditions are as
follows.
- The almost maximum torque is obtained when it is used with the pins 12 and 15 (CTL1, 2) open.
- If the torque of the motor is too low, then the applied voltage at pins 12 and 15 (CTL1, 2) are 0[V].
- When motor speed controlled, the applied voltage of the pins 12 and 15 (CTL1, 2) is between 0 and 4V.
- This IC's applied maximum voltage is 6V when V
- You must not use the applied CTL1, 2 voltage above 5.8V when V
Also, if the speed control is constant, the applied voltage of the pins 12 and 15 (CTL1, 2) is between 4 and 5V.
