Overview
The STK672-432A-E is a hybrid integrated circuit designed as a unipolar, two-phase stepping motor driver featuring PWM current control. It operates with a maximum collector-emitter voltage of 42 V and supports a maximum IGBT collector current of 2 A. The device functions within a supply voltage range of 4.75 V to 5.25 V and includes built-in overcurrent detection. It utilizes a Single In-line Package (SIP) with 19 pins, available in through-hole or surface-mount configurations depending on the specific suffix variant.
Feature Summary
- Unipolar two-phase stepping motor driver architecture
- Integrated PWM current control for precise regulation
- Built-in overcurrent detection for protection
Applications
- High-speed stepping motor control systems
- Low-voltage motor drive applications
- Industrial automation equipment requiring unipolar stepper drivers
Procurement Notes
Verify the exact suffix (e.g., -E, -BN-E) against the datasheet to confirm package type and mounting style. Confirm that the required operating temperature range aligns with the specified 0°C to +105°C limits. Ensure the application voltage stays within the 4.75 V to 5.25 V specification to guarantee proper functionality and avoid damage to the internal circuitry.
Selection Notes
Select this component when a dedicated unipolar driver with integrated protection is required. The fixed 5 V supply requirement limits use cases to compatible logic levels. Consider the SIP package dimensions for PCB layout constraints. Verify thermal management needs given the 2 A current capability and operational temperature range.
Part Context
This part belongs to the STK672 series of hybrid ICs originally developed by Sanyo Semiconductor, now part of onsemi. The series is characterized by its integration of power MOSFETs and control logic into a single package. These devices are engineered specifically for driving two-phase unipolar stepper motors with efficient current control mechanisms.
Replacement Considerations
Check for direct equivalents such as the STK672-432BN-E or STK672-632AN-E, noting differences in mounting style (through-hole vs. surface mount). Verify pin compatibility and electrical specifications before substitution.
