UC3717AN

Overview

The UC3717AN is a bipolar stepper motor driver manufactured by Texas Instruments, housed in a 16-pin PDIP package. It delivers an output current of 1 A with a quiescent supply current of 7 mA. The device operates within a supply voltage range of 10 V to 46 V and functions reliably between 0°C and +70°C. Designed for through-hole mounting, it serves as a dedicated controller and driver for stepper motor applications.

Feature Summary

• Integrated bipolar stepper motor control and drive functionality
• Built-in bootstrap circuitry for efficient high-side switching
• Thermal shutdown protection to prevent overheating damage

Applications

• Bipolar stepper motor control systems
• General-purpose motion control circuits
• Industrial automation equipment requiring precise positioning

Procurement Notes

Verify the specific suffix 'AN' corresponds to the standard PDIP-16 through-hole package configuration. Confirm that the operating temperature range meets the 0°C to +70°C requirement for the intended environment. Ensure compatibility with the 10 V to 46 V supply voltage limits before integration into the final design.

Selection Notes

Select this component when a dedicated bipolar stepper driver with integrated logic control is required. It is suitable for designs needing a single-chip solution for motor driving without external complex logic. Consider the 1 A output capability and thermal performance relative to the expected load requirements.
