Control Inputs:
- IN1, IN2: Control direction and speed of Motor 1
- IN3, IN4: Control direction and speed of Motor 2
Power Supply:
- VCC: Connected to the power supply (e.g., 12V)
- GND: Connected to ground
Protection:
- Thermal Shutdown
- Overcurrent Protection
- Undervoltage Lockout
In this circuit, the control inputs (IN1, IN2, IN3, IN4) are typically connected to a microcontroller or other control logic to manage the direction and speed of the motors. The power supply (VCC) and ground (GND) connections provide the necessary power to the motor driver and motors.
