BM6343AFS-Z中文资料36V High-performance, High-Reliability Unipolar Stepping Motor Driver数据手册ROHM规格书

描述 Description

BM6343AFS-Z is a unipolar stepping motor driver. Rated power supply voltage of the device is 36V, rated output voltage is 100V, and rated output current is 3.0A. 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.
