36 V High-performance, High-Reliability
Unipolar Stepping Motor Driver
BM6343FS-Z
General Description
Key Specifications
◼ Rated Input Voltage:
◼ Rated Output Voltage:
BM6343FS-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.
