TMC260-PA-T Integrated Circuits (ICs)

PMIC - Motor Drivers, Controllers

The TMC260-PA-T is a highly integrated, three-phase microstepping motor driver IC, designed to drive a two-phase or single-phase bipolar stepper motor system. The integrated motion controller in this device can execute all common operating modes of a stepper motor system, including microstepping, full-/half-/diagonal-copping, ramp acceleration/deceleration, positioning, and speed-controlled operation. This device is capable of being used in an industrial environment by interfacing with a wide range of control systems.

Applications

The TMC260-PA-T is ideal for a variety of applications, including printer and small motors, micro actuators and small pumps, and embedded control systems, including consumer products and office equipment such as scanners and copiers. This device can also be used in robotics, and industrial automation, where precise speed and positioning control are required. It is also suitable for instrumentation, factory automation, and motion control.

Working Principle

The TMC260-PA-T consists of two main components, the motion controller and the gate drivers. The motion controller is responsible for generating and controlling the control signals that will drive the motor. This is done by means of an internal waveform generator and a digital filter. The waveform generator is set up using the waveform parameters defined in the configuration and a profile that is programmed into the onboard EEPROM memory. The digital filter is used for the waveform generation, thereby enabling fine-grain control over the stepping motor.

The gate drivers are responsible for translating the control signals from the motion controller into the power stage inputs. This is done by using pulse width modulation (PWM) to control the gate signals of the gate drivers. By controlling the width of the pulses, the power stage input can be adjusted to the correct voltage and current levels to cause the stepper motor to rotate. In addition, the gate drivers are used to control braking of the stepper motor, allowing for faster deceleration.

The TMC260-PA-T can also be used to create a three-phase stepper motor control system. In this case, the motion controller generates three different sets of PWM signals that control the three-phase power stage inputs. Again, the PWM signals enable the power stage inputs to be adjusted to the correct voltage and current levels to cause the stepper motor to rotate.

The TMC260-PA-T is a highly integrated motor driver IC, designed to drive a two-phase or single-phase bipolar stepper motor system. It is ideal for a variety of applications, including printer and small motors, micro actuators and small pumps, and embedded control systems. With its integrated motion controller and gate drivers, the TMC260-PA-T is capable of providing precise speed and positioning control, making it a reliable and cost-effective solution for motion control applications.
