Applications

• Bipolar stepper motor control
• General motion control systems
• Ignition controller circuits

Procurement Notes

This component is officially listed as obsolete or discontinued by the manufacturer. Availability is restricted, and it may not be sold in all regions. Verify current stock status with authorized distributors before design finalization. Consider lifecycle management strategies due to end-of-life status.

Selection Notes

Select this part for low-power bipolar motor driving where a compact SOIC-8 footprint is required. Ensure the application voltage stays within the 3.8 V to 13.2 V range. Verify thermal requirements for the SOIC package under expected load conditions. Confirm compatibility with existing logic levels for drive signals.

Part Context

The SI9986 series belongs to Vishay's portfolio of integrated motor drivers. These devices combine control logic with power MOSFETs to simplify motor interface designs. The T1 suffix indicates tape and reel packaging, while E3 denotes lead-free compliance. This specific model targets cost-sensitive motion control applications.

Replacement Considerations

Officially recommended alternatives include the SIP2100DY-T1-GE3. Verify pinout and electrical specifications against the original design requirements when substituting.
