• Supports multiple micro-stepping resolutions including full, half, quarter, eighth, and sixteenth steps for enhanced precision.
• Features fully integrated power FETs and current sensing circuitry for efficient drive management.
• Provides comprehensive diagnostic status information accessible via the bus interface.

Applications

• Automotive seat adjustment mechanisms
• Active suspension systems
• Steering column actuators

Procurement Notes

Verify that the specific suffix C6216 corresponds to the required tape and reel packaging configuration and temperature grade. Confirm that the component meets AEC-Q100 automotive qualification standards relevant to your specific application environment. Ensure compatibility with the host microcontroller's LIN protocol implementation before finalizing procurement orders.

Selection Notes

Select this component when a combined driver and position controller is required to reduce bill of materials count. The integrated LIN interface allows for direct connection to vehicle networks without additional transceivers. Consider the programmable current limits and thermal dissipation characteristics of the TCPAK package when designing the PCB layout for optimal heat transfer.

Part Context

This part belongs to the AMIS-3062x family of integrated micro-stepping solutions from onsemi. It complements other variants like the AMIS-30621 which utilizes a SERIAL interface instead of LIN. The family is designed to provide flexible motion control options for automotive manufacturers seeking standardized, reliable actuator drivers.

Replacement Considerations

Direct substitutes include the AMIS-30621C6217RG for SERIAL interface applications or the NCV70627 series for similar micro-stepping requirements without integrated position control logic. Verify pinout compatibility and software register mapping differences when migrating between these specific part numbers.
