The SN75471P is a popular integrated circuit (IC) component designed for driving and controlling high-current stepper motors. It is widely used in robotics, automation, and other applications where precise motor control is required. This IC is manufactured by Texas Instruments and is capable of driving up to four bi-directional DC motors or two stepper motors simultaneously.
Key Features:
1. Dual-Half Bridge Configuration: The SN75471P IC features two H-bridge circuits, allowing bi-directional control of two DC motors or unipolar/bipolar control of one bipolar stepper motor. This configuration enables precise motor control, including speed and direction.
2. High Current Capacity: With a maximum output current rating of 1.2A per bridge, this IC can handle high-current applications where significant torque is required.
3. Overtemperature Protection: The SN75471P incorporates a built-in thermal shutdown circuit that safeguards the IC by turning off the outputs when the temperature exceeds a specified threshold. This feature prevents damage due to overheating.
4. Efficient Power Consumption: The IC employs low-power Schottky diode clamps to minimize power dissipation during motor braking or when driving inductive loads. This design ensures efficient power management and helps protect the circuit from voltage spikes
