A3958SB is a member of Pololu Robotics and Electronics’ microstepping motor driver family, which fits the PMIC (Power Management Integrated Circuits) – Motor Drivers, Controllers. This product includes a full featured microstepping motor driver which can drive up to 18V at 2A/comment and can be paired with a PWM motor controller. The integrated driver also includes a digital current limit and a back EMF compensation circuit.

The application field of A3958SB involves robotics, automated machinery, radio control vehicles, and 3D printers etc. It can be used as a controller for DC and stepper motors. The advanced microprocessor controlled on-board smart logic can drive motors in the quickest, most effective and strongest way possible. With the help of this product, a user can stay away from the complexity of programming and have precise control over the dynamical behavior of the motors.

The working principle of A3958SB is based on the principle of microstepping. Microstepping is a technique used to precisely control motors and it involves employments of smaller and more precise steps to measure the current passing through the motor. The stepper motor driver onboard A3958SB is able to manage the steady current running through the motor. This product is able to sense the torque generated between the connected motors and controllers accurately and using the on-board microprocessor it\'s able to calculate the current running in the motor. Then, it adjusts the current accordingly and thus, leads to better control over the motor. Thus, the microstepping technique employed by A3958SB allows it to achieve greater velocity and smoother motion.

Aside from the steady current running through the motor, the A3958SB is also capable of sensing the voltage running through the connected motor. This allows for the driver to provide greater control over the speed of the motor. This capability is especially useful for aiding in the acceleration and deceleration of the motors. As a result, the product produces highly controllable, smooth and uniform velocity along with better power efficiency.

Finally, the A3958SB uses a back-EMF compensation circuit in order to reduce noise caused by the motor\'s electrical activity. This circuit helps to eliminate the electrical interference caused by the motor\'s normal operation and thus, dramatically improve the overall performance and efficiency of the motor.

In conclusion, A3958SB is an advanced motor driver product which fits the PMIC (Power Management Integrated Circuits) – Motor Drivers, Controllers. It uses the microstepping technique in order to achieve better control over the motor\'s current and speed while also reducing noise generated by the motor. All these functions combine to provide higher efficiency and smoother motion in the connected motors, making this product an ideal choice for robotic, automated machinery, radio control vehicles and 3D printers.
