Overview
The STK672-531 is a hybrid integrated circuit designed for driving unipolar, two-phase stepping motors with pulse width modulation (PWM) current control. It supports both two-phase and one-two phase excitation modes selectable via the MODE pin. The device incorporates an internal current detection resistor to facilitate external motor current setting using two resistors. It features Schmitt trigger inputs compatible with 2.5V high-level signals and includes an ENABLE pin for controlling motor output while maintaining excitation timing.
Feature Summary
- Supports PWM current control for precise motor speed regulation via external clock frequency
- Selectable two-phase or one-two phase excitation modes with phase maintenance during mode switching
- Integrated current detection resistor enables simplified external current setting
- Schmitt input compatibility allows operation with 2.5V high-level logic signals
Applications
- Office photocopiers
- Printers
- Stepping motor drive systems requiring PWM control
Procurement Notes
Verify the manufacturer designation as ON Semiconductor or Sanyo Semicon Device, as historical production may involve multiple entities. Confirm the specific package type and revision level against the official datasheet to ensure compatibility with existing board layouts. Check for RoHS compliance status if required by your manufacturing standards.
Selection Notes
Select this component when a dedicated hybrid IC solution is preferred over discrete MOSFET implementations for two-phase stepper motor applications. It is suitable for designs requiring integrated current sensing and simple interface logic levels. Consider thermal management requirements due to the power dissipation inherent in hybrid driver packages.
Part Context
This part belongs to the STK672 series of thick-film hybrid ICs specifically engineered for stepping motor drives. These components are widely used in office automation equipment where reliable, compact motor control is essential. The series typically offers various variants differentiated by excitation modes and current capabilities.
Replacement Considerations
Publicly confirmed substitute part numbers for the STK672-531 were not found in the provided source material. Verify compatibility with similar models like the STK672-532 or STK672-432A-E only if their electrical characteristics and pinouts match your design requirements.
