A3967SLBTR-T Typical application Circuitry

A3967SLBTR-T

A3967SLBTR-T is an integrated chip designed for driving bipolar stepper motors, widely used in fields requiring precise motor control such as printers, scanners, CNC machines, and robotics. This chip is favored for its simple control interface, efficient current control, and microstepping capability.

Application Scenario:

In CNC machines, A3967SLBTR-T provides precise motor control, enabling high-precision positioning and smooth motion of the machine.

Parameter Features:

- Supply Voltage Range: 3V to 5.5V

- Maximum Phase Current: 750mA

- Microstepping Resolution: Up to 1/8 step

- Built-in translator simplifies stepper motor control

Specific Circuit Connection

Power Supply Connection

First, connect the VDD pin of A3967SLBTR-T (usually marked as pin 8) to a +5V power source, and the GND pins (usually pins 4 and 9) to ground. This provides the necessary operating power for the chip.

Motor Connection

Connect one end of the stepper motor coils to OUT1A (pin 2) and OUT1B (pin 3) of A3967SLBTR-T, and the other end to OUT2A (pin 11) and OUT2B (pin 14). This completes the basic motor connection.

Control Signals

Connect two output pins of the microcontroller to STEP (pin 10) and DIR (pin 13) of A3967SLBTR-T. The STEP pin receives pulse signals to drive the motor step by step, while the DIR pin controls the direction of rotation.

Microstepping Configuration

To enable microstepping, connect MS1 (pin 6) and MS2 (pin 7) of A3967SLBTR-T to appropriate logic levels. By setting the states of these pins to high or low, full-step, half-step, quarter-step, or eighth-step modes can be selected.

Design Considerations

- Current Limiting: Adjusting the current-limiting potentiometer on A3967SLBTR-T (usually located near the chip) prevents the stepper motor from overheating, thus extending its lifespan.

- Voltage Matching: Ensure that the rated voltage of the stepper motor matches the supply voltage of the driver to avoid damage to the motor or driver.

- Heat Dissipation: Under high load or high-frequency driving conditions, A3967SLBTR-T may generate significant heat. Additional heat dissipation measures such as heat sinks or fans may be necessary.

- Signal Integrity: When designing control signal wiring, consider the integrity of signals to avoid noise and interference introduced by long-distance wiring.

Through the detailed explanation above, we can observe the robust functionality and flexibility of A3967SLBTR-T in precision motor control applications. By considering factors such as current control, power supply matching, heat dissipation, and signal integrity during design, system stability and performance can be effectively enhanced.
