Description
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.
Features
- Smooth current and low acoustic noise
- Up to 1/256 micro-stepping level
- Selectable micro-stepping and current level
- Easy STEP/DIR interface
- Compact dual channel design
- Full protections
