Overview
The STK672-120H-E is a two-phase stepping motor driver hybrid IC (HIC) manufactured by onsemi. It features unipolar output configuration and supports microstepping control via PWM input. The device operates within a supply voltage range of 10 V to 45 V, with a typical operating current of 2.6 mA. It delivers an output current of 2.1 A and dissipates up to 6.5 W of power. The component utilizes a SIP-12 package for through-hole mounting and functions reliably across a temperature range of -40 °C to +105 °C.
Feature Summary
- Supports microstepping operation for enhanced motion smoothness
- Integrates flexible input logic for simplified interface design
- Provides unipolar drive capability for two-phase stepper motors
Applications
- Precision positioning systems in industrial automation
- Control circuits for office automation equipment
- Motion control modules in medical devices
Procurement Notes
Verify the specific suffix and revision level against official datasheets before procurement. Confirm availability status as this part may be subject to discontinuation or limited supply constraints. Ensure compatibility with existing PCB footprints and thermal management requirements during integration planning.
Selection Notes
Select this component when a compact, single-chip solution for two-phase unipolar stepper motors is required. Consider the SIP-12 package constraints and the 2.1 A output limit. Evaluate thermal dissipation needs given the 6.5 W power rating and operating temperature range.
Part Context
This component belongs to the STK672 series of stepping motor drivers from onsemi. The series offers various output current ratings and pin configurations tailored for different motor driving applications. The STK672-120H-E specifically targets applications requiring moderate current drive with microstepping support in a small form factor.
Replacement Considerations
Check for direct substitutes within the STK672 family such as STK672-110-E or STK672-080-E, noting differences in output current and pin count. Verify functional equivalence regarding microstepping support and supply voltage ranges before substitution.
