AMIS30532C5321RG

Overview

The AMIS30532C5321RG is a micro-stepping bipolar stepper motor driver manufactured by onsemi. It features an integrated power MOSFET technology with a supply voltage range of 6 V to 30 V and output current capability of 1.6 A. The device supports SPI interface for communication with external microprocessors. It operates within a temperature range of -40°C to 125°C and is housed in a 32-NQFP (7x7) package.

Feature Summary

• Integrated full control and power stage for bipolar stepper motors
• Micro-stepping resolution support from 1 to 1/32 steps
• On-chip voltage regulator with reset output and monitoring

Applications

• General purpose bipolar stepper motor control
• Industrial automation systems requiring precise positioning
• Embedded motion control applications

Procurement Notes

Verify component authenticity through authorized onsemi distributors or certified partners. Confirm the specific suffix RG corresponds to the required packaging configuration. Check for obsolescence status as this part may be discontinued. Ensure compatibility with existing PCB footprints for the 32-NQFP package before procurement.

Selection Notes

Select this component for applications requiring integrated drive and control logic without external power stages. Suitable for designs needing SPI-based digital control over motor parameters. Consider thermal management requirements due to integrated MOSFETs. Verify that the 1.6 A output current meets load specifications.

Part Context

Part of the AMIS-30532 family of micro-stepping drivers. Designed for high-performance stepper motor applications. Integrates analog and digital circuitry to simplify system design. Replaces discrete driver solutions with a single IC approach.

Replacement Considerations

AMIS30521C5212G is a related model in the same family but offers different electrical characteristics including 1.2 A output current and 4.75V to 5.25V supply voltage range. Verify pinout and parameter compatibility before substitution.
