Procurement Notes

Verify component status carefully as this part is officially listed as End-of-Life (EOL) by the manufacturer. Confirm availability through authorized distributors or secondary market channels. Check RoHS compliance documentation and material declarations prior to integration. Ensure that any substitute components meet the required electrical specifications and thermal performance standards for the intended application environment.

Selection Notes

Select this component for designs requiring a compact, fully integrated stepper driver solution. The 44-pin SSOP package suits space-constrained PCB layouts. Verify that the system logic levels are compatible with the parallel interface. Consider the 1.5 A output capability against the specific motor requirements. Evaluate the thermal dissipation needs given the surface mount packaging and operating temperature range constraints.

Part Context

This part belongs to the LV874x series of stepper motor drivers from onsemi. It is designed for low-voltage applications, distinguishing it from higher voltage variants in the broader product line. The series typically targets cost-effective and compact motor control solutions for consumer electronics and industrial automation devices requiring precise stepper positioning.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided source data. Due to the End-of-Life status, direct replacement verification requires consulting official obsolescence notices or contacting the manufacturer for recommended alternatives.
