AMIS30521C5212RG

Overview

The AMIS30521C5212RG is a fully integrated bipolar stepper motor driver manufactured by onsemi. It operates within a supply voltage range of 4.75V to 5.25V and supports load voltages from 6V to 30V. The device delivers an output current of 1.2A and features four half-bridge power MOSFETs in a 32-NQFP (7x7) package. It utilizes an SPI interface for control and offers step resolutions ranging from full step to 1/32 step. The junction temperature rating extends up to 172°C, ensuring robust performance in demanding environments.

Feature Summary

Fully integrated design combining control logic and power stage
SPI digital interface for precise command execution
Programmable microstepping resolution up to 1/32 step
High thermal tolerance with extended junction temperature capability

Applications

Cooling fan motor drivers
Automotive engine management systems
Industrial automation actuators

Procurement Notes

Verify component authenticity through authorized distribution channels due to the part's discontinued status. Confirm that the replacement variant matches the original pinout and electrical specifications. Review the Product Change Notification for manufacturing updates. Ensure compliance with RoHS3 standards as declared by the manufacturer. Validate package integrity upon receipt to prevent handling damage.

Selection Notes

Select this component for applications requiring precise bipolar stepper motor control via a serial interface. The high junction temperature rating allows operation in thermally constrained spaces without external cooling. The fixed 5V supply requirement limits use cases to low-voltage logic domains. Consider the discontinued status when planning long-term production cycles and evaluate alternative sources for sustained availability.

Part Context

This device belongs to the AMIS30521 family of stepper motor drivers designed for automotive and industrial reliability. It replaces earlier iterations such as the NCV70521 series. The integration of the power stage reduces board space and simplifies design complexity compared to discrete solutions. The specific C5212 suffix denotes the 32-pin QFP packaging configuration used for high-density mounting.
