AMIS30624C6244RG

Overview

The AMIS30624C6244RG is an I²C stepper motor driver and controller from onsemi, designed for precise motion control applications. It integrates a position controller with a serial interface, allowing it to function as a slave device on the bus. The component supports microstepping modes including 1/2, 1/4, 1/8, and 1/16 steps, ensuring low resonance and noise. It features programmable peak current up to 800mA and operates within a supply voltage range of 8V to 29V. The device utilizes a 20kHz PWM current control scheme with automatic selection between fast and slow decay modes. It is housed in a SOIC-20 surface-mount package and is rated for operation across a temperature range of -40°C to +125°C.

Feature Summary

• Integrates a position controller and I²C serial interface for simplified system design
• Supports multiple microstepping resolutions to reduce mechanical resonance and acoustic noise
• Features fully integrated current detection and internal flyback FETs
• Provides comprehensive diagnostic status information accessible via the serial interface

Applications

• Automotive seat adjustment mechanisms
• HVAC actuator control systems
• Industrial automation positioning tasks
• Precision instrumentation drives

Procurement Notes

Verify the specific suffix 'RG' against official documentation to confirm package type and tape-and-reel configuration. Confirm that the component meets required automotive qualification standards if used in vehicle applications. Ensure the I²C address configuration aligns with the host controller's bus architecture. Check for moisture sensitivity levels and storage conditions prior to assembly.

Selection Notes

Select this component when a combined controller and driver solution is required to minimize board space. It is suitable for applications needing high-resolution positioning without complex external logic. Consider the 800mA current limit and 29V maximum voltage when matching motor specifications. Verify compatibility with the host microcontroller's I²C interface speed and protocol requirements.

Part Context

This part belongs to the AMIS-30624 series of stepper motor drivers. The series is characterized by its integration of control and power stages. The C6244 variant specifically denotes the I²C interface version. The RG suffix typically indicates a specific packaging option, such as a reel for automated assembly, distinct from tube packaging variants.

Replacement Considerations

Check for direct substitutes within the AMIS-3062x family that may offer different interface options like LIN or SPI. Verify pin-to-pin compatibility if replacing existing designs. Ensure that any alternative component supports the required microstepping resolution and current capabilities.
