UC3770AN

Overview

The UC3770AN is a high-performance stepper motor controller and driver manufactured by Texas Instruments. It integrates a full-bridge output stage capable of delivering up to 2 A of output current. The device operates within a supply voltage range of 10 V to 45 V and draws a typical quiescent supply current of 33 mA. Designed for through-hole mounting, it is housed in a standard PDIP-16 package. The component supports an operating temperature range from 0°C to +70°C and features a single output configuration suitable for driving bipolar stepper motors.

Feature Summary

• Integrates a full-bridge power stage for direct stepper motor drive
• Supports bipolar stepper motor control applications
• Operates with a wide supply voltage range up to 45 V

Applications
