TCA3727GXUMA1

Overview

The TCA3727GXUMA1 is a fully integrated two-phase stepper motor driver manufactured by Infineon Technologies. It operates on a supply voltage range of 4.5 V to 6.5 V and supports load voltages from 5 V to 50 V. The device delivers a maximum output current of 1 A per phase and features four half-bridge outputs. It supports full, half, and quarter stepping resolutions via parallel interface control. The component is housed in a 24-SOIC package with a junction temperature operating range of -40°C to 110°C.

Feature Summary

• Integrates complete control logic and power stage for two-phase bipolar stepper motors
• Supports selectable step resolutions including full, half, and quarter steps
• Provides built-in protection mechanisms against overcurrent and thermal overload

Applications

• General purpose motion control systems
• Automotive actuator drives
• Industrial automation equipment

Procurement Notes

Verify the specific suffix 'GXUMA1' to confirm tape-and-reel packaging and RoHS compliance status. Confirm that the component is marked as obsolete or not recommended for new designs, which may impact long-term availability and production continuity. Ensure compatibility with existing design constraints before procurement.

Selection Notes

Select this component for applications requiring a compact, single-chip solution for bipolar stepper motors. It is suitable where space is limited and integration of driver and controller functions is preferred. Verify that the required supply voltage falls within the 4.5 V to 6.5 V range and that the load voltage does not exceed 50 V.

Part Context
