A4989SLDTR-T Typical application Circuitry Schematics

Allegro Microsystems' A4989SLDTR-T is a DEMOS microstepping driver with a built-in translator. Bipolar stepper motors can be used with it in full-, half-, quarter-, and sixteenth-step modes. A quick explanation of how to connect the circuit is given below:

1. Power Supply: The motor supply voltage (VM) should be connected to pin 30, and the logic supply voltage (VDD) to pin 1. Pin 16 is the ground (GND). VDD typically ranges from 3 to 5.5V, while VM can go up to 50V.

2. Motor Connections: Pins 9, 10, 27, and 28 (OUT1A, OUT1B, OUT2A, OUT2B) connect to the two coils of the bipolar stepper motor.

3. Logic Inputs: Pin 3 (STEP) is the step clock input. Each rising edge on this input will advance the motor one microstep. Pin 2 (DIR) is the direction control input. A high level causes forward stepping, while a low level causes reverse stepping.

4. Microstepping Control Inputs: Pins 5, 4, and 6 (MS1, MS2, MS3) are logic inputs that select the current decay mode and step mode.

5. Current Sense Connections: Pins 11 and 12 (IRENA, ISEN) connect to sense resistors to set the peak current.

6. Enable and Sleep Inputs: Pin 32 (NBL) is an active low input to enable all H-bridge outputs. Pin 31 (SLP\) is an active low input that minimizes power consumption by disabling internal circuitry and the output drivers when set high.

7. Pin 33 (GREG) : provides the output of the inbuilt low-dropout regulator (also known as the voltage regulator).

8. Thermal Flag: Pin 14 (FLAG) is an open-drain output that indicates over temperature shutdown.

9. Charge Pump Capacitors: Pins 25 and 26 (CP1 and CP2) need a capacitor to GND for the internal charge pump circuit.

10. Current Regulation Control: Connect a capacitor from pin 15 (VCP) to ground to set the fixed off-time period.

11. Decay Mode Selection: Pin 13 (DECAY) is a logic input that selects slow decay mode when connected to GND and selects fast decay mode when connected to VDD. Remember, it's important to always consult the data sheet of the A4989SLDTR-T for specific pin functions and more detailed information about how to use the device. Also, always follow the necessary safety precautions when working with electronic components.
