Procurement Notes

This component has been officially discontinued as per Product Change Notification OBS dated January 19, 2017. Availability is restricted to remaining stock or last-time buys. Verify end-of-life status with the manufacturer before finalizing designs. No new production runs are scheduled. Ensure compliance with RoHS and REACH regulations if applicable to your specific implementation requirements.

Selection Notes

Select this part when a dedicated stepper motor solution with integrated positioning is required. The LIN interface simplifies wiring compared to parallel or serial alternatives. Consider the 570mA output limit and 29V maximum voltage when sizing the motor. The wide operating temperature range makes it suitable for harsh environments where standard commercial components might fail.

Part Context

The AMIS30621AUA belongs to the AMIS3062x family of micro-stepping stepper motor drivers. This series includes variants like the AMIS30622 which uses a different interface. These devices are designed to replace discrete solutions, reducing board space and complexity. They are commonly used in automotive applications requiring precise motion control with minimal external components.

Replacement Considerations

As this part is obsolete, verify cross-reference availability with authorized distributors. Check pinout compatibility with potential substitutes to avoid redesigning PCB layouts. Ensure replacement parts meet the same voltage and current specifications.
