Pinout
1. Output A (Pin 1): Connects to one end of the motor.
2. Vcc (Pin 2): Supply voltage for the logic circuitry.
3. Ground (Pin 3): Ground connection.
4. Output B (Pin 4): Connects to the other end of the motor.
5. Sense (Pin 5): Used for current sensing; connect to ground through a resistor.
6. Reference (Pin 6): Internal reference voltage output.
7. Brake (Pin 7): Braking input; applying a high signal activates braking mode.
8. Direction (Pin 8): Controls the direction of the motor rotation.
9. PWM Input (Pin 9): Controls the speed of the motor using PWM signals.
10. Disable (Pin 10): Disables the H-Bridge when high.
11. Thermal Flag (Pin 11): Indicates over-temperature condition.
12. No Connection (Pin 12): Not used.
This configuration is typical for H-Bridge motor driver ICs and allows for efficient control of DC motors.
