Leadshine 
M840 
Microstepping Driver 

for Multi Phase Hybrid Stepping Motors 




High performance, low cost 
Supply voltage up to +80VDC 
Output current up to 7.8A (M880), 3.9A (M840)
Inaudible 20KHz chopping frequency
TTL compatible and optically isolated input
Automatic idle-current reduction




The M880 and the M840 are high performance microstepping drivers based on one of the  most advanced technologies in the world today. They are suitable for driving 2-phase and 4-phase hybrid stepping motors. 


By using advanced bipolar constant-current chopping technique, they can output more speed and power from 


the same motor compared with traditional drivers, such as L/R drivers. Its 3-state current control technology 


allows coil current to be well controlled with relatively small current ripple, therefore less motor heating is achieved.
