- General purpose motion control applications
Procurement Notes
This component is officially listed as End of Life (EOL) by the manufacturer. Verification of availability through authorized distributors is required, though stock may be limited or exhausted. Confirm RoHS compliance status and check for valid replacement part numbers before finalizing procurement plans.
Selection Notes
Select this component when a compact, integrated solution for bipolar stepper motors is required. It eliminates the need for external discrete drivers. Ensure the application voltage remains within the 3.8 V to 13.2 V range and that the thermal environment supports the specified junction temperature limits.
Part Context
Part of the Vishay Siliconix motor driver portfolio, specifically designed for low-power motion control. The SOIC-8 packaging facilitates space-constrained PCB layouts. It serves as a complete driver solution rather than a simple gate driver, integrating necessary protection and control features internally.
Replacement Considerations
SI9986DY-T1-E3 is documented as a recommended alternative. Verify pin compatibility and electrical specifications against the original requirements before substitution.
