AMIS30623C623BRG

Overview

The AMIS30623C623BRG is a fully integrated bipolar stepper motor driver manufactured by onsemi. It operates within a supply voltage range of 6.5V to 29V and supports step resolutions of 1/2, 1/4, 1/8, and 1/16. The device features four half-bridge outputs with a maximum output current of 570mA. It utilizes the LIN interface for communication and is housed in a 32-NQFP (7x7) package. The component is qualified to AEC-Q100 standards and functions reliably across a junction temperature range of -40°C to 165°C.

Feature Summary

• Fully integrated control and power stage for bipolar motors
• Built-in LIN interface for system communication
• AEC-Q100 automotive qualification for reliability
• Supports multiple microstepping resolutions

Applications

• Automotive seat adjustment systems
• Vehicle door lock actuators
• HVAC fan control modules
• General industrial motion control

Procurement Notes

Verify the specific suffix 'BRG' against official onsemi documentation to confirm the tape and reel packaging configuration. Ensure compatibility with existing PCB footprints for the 32-NQFP package. Confirm that the LIN protocol implementation matches the host controller requirements before finalizing procurement.

Selection Notes

Select this component when a robust, automotive-grade solution for bipolar stepper motors is required. It is suitable for applications demanding high thermal stability up to 165°C junction temperature. Consider the 570mA output capability and 29V maximum voltage limit to ensure they align with the motor's electrical specifications and system power budget.

Part Context

This part belongs to the AMIS-30623 series from onsemi, designed specifically for automotive and industrial motor control. The series integrates advanced protection features and diagnostic capabilities. The C623BRG variant specifically denotes the 32-pin NQFP package with exposed pad construction, optimized for thermal performance and surface mount assembly processes.

Replacement Considerations

The AMIS30623C623BG is a documented alternative offering identical functional characteristics but packaged in a 32-VQFN format. Verify pin-to-pin compatibility and thermal dissipation requirements when substituting between the NQFP and VQFN packages.
