Monolithic Digital IC  
PWM Current Control  
LB1945D  
Stepping Motor Driver  
Overview  
The LB1945D is a PWM current control stepping motor driver that uses a bipolar drive technique. It is optimal for use with  
the carriage and paper feed stepping motors used in printers.  
Functions and Features  
• PWM current control (external clock)  
• Digital load current selection function (supports 1-2, W1-2, and 2-phase excitation)  
• Built-in high and low side diodes  
• Simultaneous on state prevention function (through-current prevention)  
• Built-in thermal shutdown circuit  
• Noise canceling function
