A3966SLBTR-T Typical application Circuitry Schematics

A motor driver chip that can be used to manage stepper motors is the A3966SLBTR-T. The Allegro A3966 is designed to interface directly with 8-bit microprocessors and can drive a wide range of stepping motors, from miniatures with phase resistances of a few ohms to larger stepping motors with phase resistances up to 50 ohms. An application circuit for this chip can be something like this:

1.Power Supply: Connect power (VBB) to pin 8 of the A3966. The ground (GND) is connected to pins 4 and 5. The chip requires a logic supply voltage (VCC) on pin 1, which is typically 3 to 5.5 V.

2. Motor Connections: Pins 3 and 6 are OUT1A and OUT1B and they connect to one coil of the stepper motor. Similarly, pins 2 and 7 are OUT2A and OUT2B and they connect to the other coil of the stepper motor.

3. Logic Inputs: Pins 11 and 14 are phase inputs (PHASE1 and PHASE2), and pins 10 and 13 are enable inputs (ENABLE1 and ENABLE2). These can be connected to the control signals from your microcontroller or other control circuit. The phase inputs determine the current direction through each motor coil, and the enable inputs can be used to enable or disable the outputs.

4. Clock Inputs: Pins 12 and 15 are clock inputs (CLOCK1 and CLOCK2). When these pins see a rising edge, the chip will make one step, the direction of which is determined by the phase inputs.

5. Sensing and Chopping Control: Pins 9 and 16 are sense inputs (SENSE1 and SENSE2), and they should be connected to a sense resistor, which is used to limit the current through the motor.

This resistor's value is determined by the supply voltage and the required current limit. Pins 17 and 18 are for chopping control (RC1 and RC2), which can be connected to a capacitor and resistor to set the chopping frequency. Please remember to consult the datasheet of the A3966 for specific pin functions and more detailed information about how to use the chip. Also, always use appropriate safety precautions when working with electronic components.
