UC3717  
Stepper Motor Drive Circuit  
FEATURES  
DESCRIPTION  
Half-step and Full-step Capability  
The UC3717 has been designed to control and drive the current in  
one winding of a bipolar stepper motor. The circuit consists of an LS-  
TTL-compatible logic input, a current sensor, a monostable and an  
output stage with built-in protection diodes. Two UC3717s and a few  
external components form a complete control and drive unit for LS-  
TTL or micro-processor controlled stepper motor systems.  
Bipolar Constant Current Motor Drive  
Built-in Fast Recovery Schottky  
Commutating Diodes  
Wide Range of Current Control 5-1000mA  
Wide Voltage Range 10-45V  
The UC1717 is characterized for operation over the full military tem-  
perature range of -55°C to +125°C, the UC2717 is characterized for  
-25°C to +85°C, and the UC3717 is characterized for 0°C to +70°C.
