Overview
The STK6713AMK4-M-E-SY is a thick film hybrid integrated circuit designed as a unipolar fixed-current chopper-type driver for four-phase stepping motors. Manufactured by ON Semiconductor, it utilizes a single in-line package (SIP) with sixteen terminals and a 2.54 mm pitch. The device operates within a power supply range of 5 V to 36 V. It integrates the necessary control logic and power output stages required to drive stepper motor coils efficiently without external complex circuitry.
Feature Summary
- Integrates unipolar fixed-current chopper control technology for precise motor driving
- Designed specifically for four-phase stepping motor applications
- Constructed using thick film hybrid technology for robust performance
- Provides a complete solution in a compact single in-line package
Applications
- Four-phase stepping motor control systems
- Industrial automation equipment requiring precise positioning
- Unipolar motor drive circuits in embedded systems
Procurement Notes
Verify the manufacturer designation, as this component is currently produced by ON Semiconductor following corporate restructuring. Confirm the specific suffix matches the requested packaging and tape-and-reel specifications. Ensure the source documentation explicitly identifies the part as a hybrid IC to distinguish it from monolithic alternatives. Cross-reference the ordering number EN4847 with official distributor catalogs to confirm current availability status and compliance certifications.
Selection Notes
Select this component when a dedicated hybrid solution for four-phase unipolar stepper motors is required. It is suitable for designs needing integrated chopper current control to reduce heat and improve efficiency at lower speeds. Consider the 5 V to 36 V operating range to ensure compatibility with the system's power supply architecture. Evaluate the SIP16 footprint constraints against the printed circuit board layout requirements before finalizing the design.
Part Context
This part belongs to the STK series of hybrid motor drivers developed originally by Sanyo Electric and now managed by ON Semiconductor. These devices are engineered to replace discrete transistor-based driver circuits, offering higher reliability and reduced board space. The STK6713AMK4 variant specifically targets four-phase configurations, distinguishing it from bipolar or two-phase counterparts in the same family.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Verify pinout compatibility and thermal characteristics if considering alternative hybrid drivers from other manufacturers.
