Instructions for TB67S158:

1. Power Supply Connection:

   • Connect the supply voltage (VCC) between 4.5V and 18V.
   • Ensure the logic supply voltage (VIO) is within the range of 2.7V to 5.5V.

2. Motor Control:

   • Use the IN1 and IN2 pins to control the direction of the motor by applying appropriate logic levels.
   • The PWM input can be used to control the speed of the motor.

3. Current Limitation:

   • Do not exceed the continuous output current of 1.2A per channel.
   • Be cautious of peak currents; they should not exceed 2.5A.

4. Thermal Management:

   • Monitor the operating temperature to ensure it does not exceed 125掳C.
   • If thermal shutdown activates at approximately 160掳C, allow the device to cool before resuming operation.

5. Protection Features:

   • The TB67S158 includes overcurrent protection, thermal shutdown, and undervoltage lockout features to protect the device from damage.

6. Layout Considerations:

   • Place the heat sink or cooling solution near the power stage to dissipate heat effectively.
   • Keep the ground plane solid and wide to reduce inductance and improve noise immunity.

7. Signal Integrity:

   • Use short and direct traces for high-frequency signals like PWM to minimize noise and interference.
   • Decouple VCC and VIO with capacitors close to the IC to stabilize the power supply.

By following these guidelines, you can ensure reliable and efficient operation of the TB67S158 motor driver.
