Instructions for Using TB6612FNG

1. Power Supply:

   • Connect the VCC pin to a power supply between 2.0V and 5.5V.
   • Ensure the power supply can provide sufficient current to drive the motors.

2. Ground Connection:

   • Connect the GND pin to the ground of your power supply and control circuit.

3. Motor Control:

   • The TB6612FNG has two motor drivers (A and B) with the following control pins:
     • AIN1 and AIN2: Control the direction of Motor A.
     • BIN1 and BIN2: Control the direction of Motor B.
     • PWMA and PWMB: Control the speed of Motor A and Motor B using PWM signals.

4. Standby Mode:

   • Set the STBY pin to HIGH to enable the motor drivers.
   • Set the STBY pin to LOW to put the motor drivers into standby mode, reducing power consumption.

5. Direction Control:

   • To rotate Motor A forward, set AIN1 to HIGH and AIN2 to LOW.
   • To rotate Motor A backward, set AIN1 to LOW and AIN2 to HIGH.
   • To stop Motor A, set both AIN1 and AIN2 to LOW.
   • Similar control applies to Motor B using BIN1 and BIN2.

6. Speed Control:

   • Apply a PWM signal to PWMA to control the speed of Motor A.
   • Apply a PWM signal to PWMB to control the speed of Motor B.
   • The duty cycle of the PWM signal determines the speed of the motor.

7. Brake Mode:

   • To brake Motor A, set both AIN1 and AIN2 to HIGH.
   • To brake Motor B, set both BIN1 and BIN2 to HIGH.

8. Current Limiting:

   • The maximum output current per channel is 1.2A. Ensure that the load does not exceed this limit to avoid damage to the IC.

9. Thermal Management:

   • The TB6612FNG can dissipate up to 1.7W of power. Use a heatsink if operating at high currents or in high ambient temperatures to prevent overheating.

10. Pin Configuration:

    • Refer to the datasheet for the detailed pin configuration and layout of the TB6612FNG.

11. Protection Features:

    • The TB6612FNG includes overcurrent protection, thermal shutdown, and undervoltage lockout to protect the IC from damage.

By following these instructions, you can effectively use the TB6612FNG to control DC motors in your projects.
