With the acceleration of industrial automation, motor drives have become an indispensable part of modern electronic products. To control motor drives effectively and efficiently, motor drivers, controllers such as TMC2130-LA-T have been increasingly utilized. This article explains the application field and working principle of TMC2130-LA-T.

TMC2130-LA-T belongs to PMIC (Power Management Integrated Circuit) motor drivers, controllers. It is a powerful embedded driver designed to drive motion systems with a single-axis architecture in more diverse applications. It was first introduced in 2012 and is currently gaining tremendous popularity due to its efficient performance and versatile features.

The applications of TMC2130-LA-T cover a wide range including 3D Printer, Robotics, Scanner, Laser Engraver, Electronic Music Instruments, Industrial Automation, CNC Automation, etc. This motor driver features adjustable power modes with high power efficiency, 3-sets of current control, step-and-direction control, four-channel interface for controlling two axes of stepper motors, and overcurrent protection. Moreover, the chip supports SPI communication interface with high data security.

TMC2130-LA-T works with the concepts of Command, Status and Data. Accurately speaking, it has two parts of the unit, one is referred to as the Command Unit and another is the Status Unit. The Command Unit is responsible for distributing parameters, performing shifting operations and setting up specific conditions, while the Status Unit sends back parameters, voltage signals and current signals to the Command Unit in order to increase the whole efficiency.

The major components of TMC2130-LA-T include North/South Bridges, Digital logic interface and Three-quarter bridge circuit. The North and South bridge is used to supply power to the motor, the Digital logic interface receives the control signals from the outside, turns it into electrical signals and controls the motor at the same time. The Three-quarter bridge circuit serves as an interface between the motor and the outside world, providing a signal conversion from the motor driver to the outside world, allowing for the control of the motor.

TMC2130-LA-T also features a few built-in features that provide motor control with ease. These include: adjustable S/D input delay times, over/under current and temperature protections, adjustable current control, step and direction controls, adjustable current control settings, and adjustable PWM and analogue current regulation.

In brief, TMC2130-LA-T is a PMIC motor driver, controller specifically designed to drive motion systems with a single-axis architecture. This motor driver provides efficient power management and exceptional performance, supported with adjustable power modes, three-sets of current control, step-and-direction control, four-channel interface for controlling two axes of stepper motors, and overcurrent protection. With its wide applications, this motor driver has been widely adopted for industrial automation, electronic music instruments, CNC automation, robotics and 3D printing.
