Integrated Circuit  
Module, 4 Phase Stepping Motor Driver, 1.75A  
Features:  
D Low heat generation due to constant current chopper system.  
D Functions of pause action and power down.  
D Able to be used in any stepping motor of hybrid typ, P.M. type, V.R. type.  
D Inverter buffer provides direct drive, for 4 phase dual excitation.  
D Built in sensing power resistors for load current.  
D Protection elements for fly–back voltage are included.
