UC3717AQG3

Overview

The UC3717AQG3 is a bipolar stepper motor driver manufactured by Texas Instruments. It features a half-bridge output configuration with two channels, each capable of delivering an output current of 1 A. The device operates within a supply voltage range of 4.75 V to 5.25 V for logic and supports load voltages from 10 V to 46 V. It is housed in a 20-PLCC package (9x9 mm) and is designed for surface mount installation. The component functions as a general-purpose stepper motor controller.

Feature Summary

Integrated bootstrap circuitry for high-side drive management
Built-in overtemperature fault protection mechanism
Logic interface compatible with standard control signals

Applications

General purpose stepper motor control systems
Bipolar stepper motor driving applications

Procurement Notes

Verify the specific suffix 'G3' against official manufacturer documentation to confirm RoHS compliance status and exact pinout compatibility. Ensure the selected package variant matches the target PCB footprint requirements. Cross-reference the datasheet revision history for any functional updates or recommended design changes prior to finalizing the procurement order.

Selection Notes

Select this component for designs requiring a dedicated bipolar stepper driver with integrated protection features. Consider the 20-PLCC package constraints for layout planning. Evaluate thermal performance under maximum load conditions given the 1 A output capability. Confirm that the system logic levels are compatible with the specified input interface requirements.

Part Context

This part belongs to the UC3717A family of stepper motor controllers. It serves as a specialized power management IC within the broader PMIC category. The device integrates gate drive capabilities specifically optimized for stepping motors, distinguishing it from general-purpose MOSFET drivers.
