PBL 3717/2  
Stepper Motor  
Drive Circuit  
Description  
Key Features  
PBL 3717/2 is a bipolar monolithic circuit intended to control and drive the current in  
one winding of a stepper motor.  
The circuit consists of a LS-TTL compatible logic input stage, a current sensor, a  
monostable multivibrator and a high power H-bridge output stage with built-in  
protection diodes.  
Two PBL 3717/2 and a small number of external components form a complete  
control and drive unit for LS-TTL or microprocessor-controlled stepper motor  
systems.  
Half-step and full-step modes.  
Switched mode bipolar constant  
current drive.  
Wide range of current control  
5 - 1200 mA.  
Wide voltage range 10 - 50 V.  
Designed for unstabilized motor  
supply voltage.  
Current levels can be selected in  
steps or varied continuously.  
Thermal overload protection.  
Built-in recirculation diodes.
