AMIS30512C5122G

Overview

The AMIS30512C5122G is a fully integrated bipolar stepper motor driver manufactured by onsemi. It operates within a supply voltage range of 6V to 30V and supports step resolutions from full step to 1/32 microstepping. The device utilizes a Power MOSFET technology and features an SPI interface for control. It is housed in a 24-SOIC package with four half-bridge outputs. The component is designed for surface mount installation and functions reliably across a junction temperature range of -40°C to 160°C.

Feature Summary

• Fully integrated design combining control logic and power stages
• Supports variable step resolution up to 1/32 microstepping
• Serial Peripheral Interface (SPI) communication capability
• High thermal tolerance suitable for demanding environments

Applications

• General purpose bipolar stepper motor control
• Industrial automation systems
• Cooling fan motor drivers

Procurement Notes

Verify current availability status as the part may be discontinued or subject to limited stock. Confirm that the 24-SOIC package dimensions match your PCB footprint requirements. Ensure the SPI interface protocol aligns with your system controller. Check for RoHS compliance documentation if required for your specific manufacturing standards.

Selection Notes

Select this component when a single-chip solution for bipolar stepper motors is required. It is suitable for applications needing high operating temperatures up to 160°C junction. Consider the SPI interface if digital control precision is necessary. Verify that the 6V to 30V supply range matches your system power architecture.
