- Relay drivers
- Solenoid drivers
- High current LED drivers
- Automotive applications
Usage:
- Connection:
- Connect VCC1 to the logic voltage (4.5V to 7V).
- Connect VCC2 to the motor voltage (4.5V to 36V).
- Connect the input pins (IN1, IN2, IN3, IN4) to the microcontroller or control logic.
- Connect the output pins (OUT1, OUT2, OUT3, OUT4) to the motor terminals.
- Enable the channels by connecting the enable pins (EN1, EN2) to the logic high or via PWM signals for speed control.
- Control:
- Use the input pins to set the direction of the motor rotation.
- Use PWM on the enable pins to control the speed of the motors.
- Protection:
- Ensure proper heat sinking or cooling as the IC can get hot under high loads.
- Use external diodes if necessary to protect against back EMF generated by motors.
Caution:
- Ensure the total current does not exceed the maximum ratings of the IC.
- Provide adequate cooling to prevent thermal shutdown.
- Avoid short circuits and excessive voltage spikes.
