AMIS30622C6227G

Overview

The AMIS30622C6227G is a bipolar stepper motor driver and controller from onsemi, designed for automotive applications. It integrates a position controller with an I²C interface, allowing it to function as a slave device on a bus. The device supports microstepping resolutions of 1/2, 1/4, 1/8, and 1/16. It operates within a supply voltage range of 6.5 V to 29 V and delivers a peak output current of up to 800 mA. The component is qualified to AEC-Q100 standards and functions across a temperature range of -40°C to +165°C.

Feature Summary

• Integrates a programmable position controller and diagnostic interface with I²C communication capability.
• Supports microstepping modes including 1/2, 1/4, 1/8, and 1/16 steps for high resolution.
• Features automatic selection between fast and slow decay modes to reduce resonance and noise.

Applications

• Automotive seat positioning systems
• Vehicle mirror adjustment actuators
• Throttle body control mechanisms

Procurement Notes

Verify the specific suffix C6227G against official datasheets to confirm package type and tape/reel specifications. Confirm end-of-life status or obsolescence notices prior to design-in, as availability may be restricted. Ensure compatibility with existing I²C bus protocols and voltage levels in the target system architecture.

Selection Notes

Select this component when an integrated solution combining motor driving and position control via I²C is required. It is suitable for applications needing reduced resonance and noise through automatic decay mode selection. Consider alternative packages if different pin counts or thermal performance are needed, such as the NQFP variant.

Part Context

This part belongs to the AMIS-3062x family of micro-stepping stepper motor drivers. The series includes variants with LIN interfaces (AMIS-30621) and I²C interfaces (AMIS-30622). These devices are designed to simplify motion control by integrating power stages and control logic into a single chip.

Replacement Considerations

Check for direct substitutes within the AMIS-3062x family, such as AMIS30622C622BG, which may offer different packaging options like QFP instead of SOIC. Verify functional equivalence regarding interface types and current ratings before substitution.
