Procurement Notes

This component is officially listed as End-of-Life (EOL) by the manufacturer. Distribution channels indicate limited or unavailable stock in many regions. Buyers must verify current availability status directly with authorized suppliers before design finalization. Due to discontinuation, long-term supply cannot be guaranteed, and alternative sourcing strategies should be evaluated immediately.

Selection Notes

Engineers should consider this part only for legacy system maintenance or non-critical new designs where EOL status is acceptable. Verify that the 1.5 A current rating and 45 V load voltage meet specific application requirements. Ensure the DIP-28 package fits the PCB layout constraints. Since the product is discontinued, assess the risk of future production interruptions and plan for potential redesigns if long-term support is required.

Part Context

The LB11847L-E belongs to onsemi's portfolio of motor controllers and drivers, specifically targeting bipolar stepper motors. It falls under the Power Management ICs subcategory but serves motion control functions. The series provides integrated solutions for driving stepper motors without external power transistors, simplifying circuit design for moderate-power applications in various electronic systems.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. As the LB11847L-E is marked as End-of-Life, engineers must identify compatible alternatives based on pinout, current ratings, and voltage specifications from other manufacturers or newer onsemi products.
