This step motor driver board which is prdouced by ON Semiconductor has AMIS-30543 driver IC on it. Current limitation via SPI, 11 different step mode(from full step to 1/128 step), reverse-WMF feedback for use closed cycle or detect forced, over current protection and over heat protection is available. Operation voltage range is 6-30V. Board can give 1.8A without aluminium cooler, 3A with cooler for each phase.
- Standard current and direction control interface
- Access to calibration and situation registers with SPI interface
- Speed and charge angle feedback for forced detection and lose cycle usage
- 11 different current mode farklı adım modu (full step-1 phase compensation, full step-2 phase compensation, half step, quarter step,1/8 step, 1/16 step, 1/32 step, 1/64 step and 1/128 step)
- Configurable current control(132mA - 3A) via SPI.
- Slowdown mode options
- Board works with 3.3V and 5V logic levels
- Board can supply microcontroller wit enternal 5V regulator
- Internal watchdog function
- Open coil detection
- Warns you before shut down at over heat situation
- Shut down at over heat situtation
