Procurement Notes

Verify end-of-life status before design finalization as the manufacturer indicates this part is obsolete. Confirm AEC-Q100 compliance requirements with your specific application standards. Check for available replacement components from onsemi's current portfolio. Ensure compatibility with existing PCB layouts if substituting. Validate thermal management needs given the high maximum operating temperature specification.

Selection Notes

Select this component when a robust, automotive-grade stepper driver with LIN connectivity is required. Consider the 800 mA output current limit for load matching. Evaluate the SOIC-20 package constraints against board space limitations. Assess the need for microstepping resolution versus simpler drive modes. Verify that the 6.5 V minimum supply voltage aligns with system power rails.
