Overview
The STK672-520 is a unipolar two-phase full and half-stepping motor driver integrated circuit manufactured by onsemi. It is housed in a 12-SIP (Single In-line Package) configuration designed for direct interface with microcontrollers. The device integrates power MOSFETs to drive stepper motors, simplifying system design by reducing component count. It supports both full-step and half-step operation modes for precise motion control applications.
Feature Summary
- Integrates power MOSFETs for direct stepper motor driving
- Supports unipolar two-phase full and half-stepping configurations
- Designed for simplified microcontroller interfacing
Applications
- Unipolar stepper motor control systems
- Two-phase stepping motor drivers
- Motion control modules requiring integrated power switching
Procurement Notes
Verify the current lifecycle status before procurement as this component may be obsolete. Confirm package compatibility with existing PCB footprints. Ensure supply chain sources provide authentic onsemi products. Check for alternative replacement parts if availability is limited. Validate technical specifications against original design requirements.
Selection Notes
Select this component for applications requiring a dedicated unipolar stepper motor driver with integrated power stages. Consider the 12-SIP package constraints during mechanical design. Evaluate thermal management needs based on the integrated MOSFET architecture. Compare performance requirements against newer generation drivers if available.
Part Context
The STK672 series was originally developed by SANYO Semiconductor, which later became part of onsemi through acquisition. This specific model represents a legacy solution for unipolar stepper motor applications. The series includes evaluation boards for development purposes. Understanding the historical context aids in identifying compatible documentation and support resources.
Replacement Considerations
Check for official onsemi recommended replacements or cross-reference equivalents. Verify pin-to-pin compatibility if substituting directly. Review updated datasheets for any functional changes in successor models.
