TIDA-00641 Reference Design

Texas Instruments

Dual High Resolution Micro-stepping Driver Reference Design


This reference design achieves a dual channel high resolution micro-stepping driver module using PWM current regulation method. Selectable micro-stepping level and current level is provided with the on-board switches. The PWM regulation scheme gives smooth phase current and ultra-low acoustic operation noise. Protections such as over current: over temperature: and short outputs are all provided along with the DRV8848 device.
