AMIS30512C5122RG

Overview

The AMIS30512C5122RG is a fully integrated bipolar stepper motor driver manufactured by onsemi. It operates within a supply voltage range of 6V to 30V and utilizes a 24-SOIC surface-mount package. The device supports step resolutions from full step to 1/32 microstepping via an SPI interface. Designed for robust performance, it functions across a junction temperature range of -40°C to 160°C. This component integrates control logic and power stages into a single chip.

Feature Summary

• Fully integrated design combining control logic and power MOSFET output stages
• Programmable microstepping resolution ranging from full step to 1/32
• Serial Peripheral Interface (SPI) for digital configuration and control
• High thermal stability supporting operation up to 160°C junction temperature

Applications

• General purpose bipolar stepper motor control systems
• Industrial automation equipment requiring precise positioning
• Office automation devices such as printers and scanners

Procurement Notes

Verify the specific suffix 'RG' against official documentation to confirm packaging details, as distributors may list standard variants. Confirm current availability status, as this part number has been marked as obsolete in public records. Ensure compatibility with existing PCB footprints for the 24-SOIC package before procurement planning.

Selection Notes

Select this component for applications requiring a compact, fully integrated solution for bipolar stepper motors. It is suitable where SPI communication is preferred over parallel interfaces for configuration. Consider the high operating temperature range for environments with limited cooling. Verify that the 6V to 30V supply range matches the system power architecture.

Part Context

This part belongs to the AMIS30512 family of stepper motor drivers. It shares core functionality with variants like the AMIS30512C5122G but differs in packaging or tape-and-reel specifications. The family is designed for general-purpose motor control applications requiring integrated power handling and digital interface capabilities.

Replacement Considerations

Public records indicate the AMIS30512C5122RG is obsolete. The AMIS30512C5122G is listed as a related variant within the same product family. Evaluate the C5122G for functional equivalence, noting potential differences in packaging or reel specifications.
