UC3770A  
UC3770B  
High Performance Stepper Motor Drive Circuit  
FEATURES  
DESCRIPTION  
Full-Step, Half-Step and Micro-Step  
Capability.  
The UC3770A and UC3770B are high-performance full bridge driv-  
ers that offer higher current and lower saturation voltage than the  
UC3717 and the UC3770. Included in these devices are LS-TTL  
compatible logic inputs, current sense, monostable, thermal shut-  
down, and a power H-bridge output stage. Two UC3770As or  
UC3770Bs and a few external components form a complete micro-  
processor-controllable stepper motor power system.  
Bipolar Output Current up to 2A.  
Wide Range of Motor Supply Voltage:  
10–50V  
Low Saturation Voltage  
Unlike the UC3717, the UC3770A and the UC3770B require exter-  
nal high-side clamp diodes. The UC3770A and UC3770B are  
identical in all regards except for the current sense thresholds.  
Thresholds for the UC3770A are identical to those of the older  
UC3717 permitting drop-in replacement in applications where  
high-side diodes are not required. Thresholds for the UC3770B are  
tailored for half stepping applications where 50%, 71%, and 100%  
current levels are desirable.  
Wide Range of Current Control: 5mA–2A.  
Current Levels Selected in Steps or Varied  
Continuously.  
Thermal Protection and Soft Intervention.  
The UC3770A and UC3770B are specified for operation from 0°C  
to 70°C ambient.
