POWERSTEP01TR

Overview

The POWERSTEP01TR is a system-in-package stepper motor controller and driver from STMicroelectronics, housed in a VFQFPN-9 SMD/SMT package. It integrates an SPI programmable microstepping controller with dual low RDS(on) full-bridge power MOSFETs. The device supports a supply voltage range of 7.5 V to 85 V, delivering up to 10 A output current. It operates at a frequency of 16 MHz with a maximum operating temperature of +150°C and minimum of -40°C. The unit draws 50 mA working supply current and provides 2 outputs.

Feature Summary

• Integrates an SPI programmable digital control core for generating user-defined motion profiles including acceleration, deceleration, speed, and target positioning calculations.
• Features a dual low RDS(on) full-bridge with embedded non-dissipative overcurrent protection and comprehensive safety mechanisms such as thermal, low bus voltage, and motor stall detection.
• Supports both voltage mode driving and advanced current control modes to accommodate diverse application requirements.

Applications

• Industrial applications requiring robust stepper motor control
• High-power bipolar stepper motor driving systems
• Multi-motor solutions compatible with STM32 Nucleo boards

Procurement Notes

Verify the specific ordering suffix to confirm the TR variant corresponds to reel packaging rather than tray distribution. Confirm moisture sensitivity handling procedures are followed during storage and assembly. Ensure the selected part number matches the required output current and voltage specifications for the target stepper motor application before procurement.

Selection Notes

Select this component when a highly integrated solution combining control logic and power stages is required. It is suitable for designs needing full digital motion control via SPI without external discrete drivers. Consider the VFQFPN-9 package constraints and thermal management capabilities for high-current operation up to 10 A within the specified temperature range.

Part Context

This part belongs to the powerSTEP01 series, designed for stepper motor applications. It represents a system-in-package approach that consolidates the microstepping controller and power MOSFETs into a single compact unit. This integration simplifies design complexity while providing high performance and reliability for demanding motor control tasks.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing evaluation boards like EVLPOWERSTEP01 or X-NUCLEO-IHM03A1 if migrating from other variants within the same product line.

FAQ

How is the motion profile programmed?

The digital control core generates user-defined motion profiles with acceleration, deceleration, speed, or target position through a dedicated register set accessible via a standard 5-Mbit/s SPI interface.

What protection features are included?

The device includes a rich set of protections such as thermal shutdown, low bus voltage detection, embedded non-dissipative overcurrent protection, and sensorless motor stall detection.
