STMicroelectronics L6472PDTR - Fully Integrated Microstepping Motor Driver

The L6472PDTR from STMicroelectronics is a state-of-the-art, fully integrated microstepping motor driver designed to deliver precise control for a wide range of motion applications. This advanced system-in-package solution is part of STMicroelectronics' motion control product line, which is renowned for its high performance, reliability, and ease of use.

Enclosed in a compact PowerSO-36 package, the L6472PDTR is capable of driving bipolar stepper motors with a voltage range from 8 V to 45 V and output current up to 3 A. Its integrated dual full-bridge gate drivers employ adaptive decay mode control, ensuring smooth and efficient motor operation. The device is capable of performing up to 1/16 microstepping, which allows for high-resolution control and reduces mechanical resonance, resulting in quieter and more precise motor motion.

One of the key features of the L6472PDTR is its integrated non-dissipative overcurrent protection, which enhances the safety and longevity of the motor driver. Additionally, the motor driver includes thermal shutdown and undervoltage lockout features, further protecting the device and the system it is integrated into. Its built-in SPI interface facilitates communication with a host microcontroller, enabling users to configure and control the motor driver with ease.

The L6472PDTR also boasts a range of diagnostic features. These include stall detection and a feedback system that provides information on the state of the device, which is crucial for applications where reliability is paramount. The driver is perfect for applications such as 3D printers, CNC machines, robotics, and other precision motion control systems, where high torque, fine resolution, and reliable operation are required.

STMicroelectronics provides comprehensive support for the L6472PDTR, including evaluation boards and a suite of software tools that enable rapid development and prototyping. This ensures that designers can leverage the full potential of the motor driver and significantly reduce time-to-market for their motion control solutions.
