Application Notes
- Improved Thermal Dissipation and Energy Efficiency for Peripheral DrivingPDF, 330 Kb, File published: Oct 30, 2014
- Stepper Motor Driving with Peripheral Drivers (Rev. A)PDF, 172 Kb, Revision: A, File published: Dec 2, 2016
This application report describes in detail how to interface stepper motors with TI peripheral drivers. Primarily, this report discusses how to connect and drive stepper motors, including the stepper motor driving patterns. Advantages and disadvantages to each stepping pattern are discussed; and logic tables, timing diagrams, and pictorial representations of each driving pattern are provided.
