Procurement Notes
Verify the specific suffix 'Z' against the manufacturer's latest documentation to confirm compliance with RoHS3 standards and lead time requirements. Ensure the ordering part number matches the exact package variant required for your PCB layout. Cross-reference the datasheet revision date to confirm all electrical characteristics remain consistent with your design specifications before finalizing procurement.
Selection Notes
Select this component when a compact solution for bipolar stepper motors is needed with integrated power MOSFETs. Consider the 1.5A continuous output current limit and the 35V maximum supply voltage. Evaluate the thermal performance given the QFN package size and the specified junction temperature range. Confirm compatibility with the host controller's logic levels and step resolution requirements.
Part Context
This part belongs to the MP6600 series of stepper motor drivers. It is functionally similar to the MP6600GR-P but may differ in packaging or environmental compliance status. The 'LGR' designation typically indicates specific pinout or package variations within the MPS portfolio. Check for direct substitutes like the MP6600GR-P if availability is an issue, ensuring pin compatibility.
Replacement Considerations
The MP6600GR-P is listed as a parameter-equivalent substitute. Verify pin-to-pin compatibility and identical electrical specifications before substitution. Ensure the replacement part meets the same thermal and voltage requirements for the application.
