BM6343AFS-Z (New) Unipolar Stepping Motor Driver

Industrial

36V High-performance, High-Reliability Unipolar Stepping Motor Driver

BM6343AFS-Z is a unipolar stepping motor driver. Rated power supply voltage of the device is 36 V, rated output voltage is 100 V, and rated output current is 3.0 A. CLK-IN Driving Mode and 3-wire Serial Communication Mode is adopted for input interface, and excitation mode is corresponding to FULL STEP mode, HALF STEP mode and QUARTER STEP mode via a built-in DAC. In addition, the power supply may be driven by one single system, which simplifies the design.
