Overview
The STK672-631A-E is a stepper motor driver from onsemi, designed for single-pole output configurations. It operates within a supply voltage range of 4.75V to 5.25V and supports load voltages up to 46V. The device delivers an output current of up to 1.2A and features a typical switching frequency of 47kHz. Housed in a SIP package with 15 pins, it is intended for through-hole mounting. The component functions as a dedicated controller and driver for stepping motors.
Feature Summary
- Integrated single-pole output configuration for direct stepper motor control
- Built-in logic and drive circuitry for simplified system design
- Operates on standard 5V logic supply levels
Applications
- Stepper motor control systems
- Motion control applications
- Industrial automation equipment
Procurement Notes
Verify the specific suffix 'E' against official documentation to confirm package and temperature grade. Confirm availability status as some sources indicate this product may be no longer manufactured. Ensure the selected variant matches the required pin count and thermal specifications for the target application.
Selection Notes
Select this component for applications requiring a single-pole stepper motor interface with moderate current demands. Verify that the 1.2A output capability meets the motor's phase requirements. Consider the SIP package constraints for PCB layout and thermal management compared to alternative surface-mount solutions.
Part Context
This part belongs to the STK672 series of stepper motor drivers by onsemi. The series includes variants like STK672-630AN-E and STK672-070-E, which differ in current ratings and pin counts. These devices are typically used in embedded motion control systems where integrated driving and logic are preferred over discrete solutions.
Replacement Considerations
Check for direct substitutes within the STK672 family or other onsemi stepper drivers. Verify compatibility with existing board layouts due to potential differences in SIP pin configurations and dimensions.
