PBL 377 70/1  
High Performance  
Stepper Motor Drive Circuit  
Key Features  
Description  
Half-step and full-step operation.  
PBL 377 70/1 is a bipolar monolithic circuit intended to control and drive the current in  
one winding of a stepper motor. It is a high power version of PBL 377 17/1 and  
special care has been taken to optimize the power handling capability without  
suffering in reliability.  
Switched mode bipolar constant  
current drive  
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. The circuit is  
pin-compatible with the PBL 3717/2 industry-standard driver.  
Two PBL 377 70/1 and a small number of external components form a complete  
control and drive unit for LS-TTL or microprocessor-controlled stepper motor  
systems.  
Wide range of current control  
5 -1800 mA.  
Wide voltage range 10 - 60 V.  
Designed for unstabilized motor  
supply voltage.  
Current levels can be selected in  
steps or varied continuously.  
Thermal overload protection.
