com Overview The STK672-040-E is a stepping motor driver hybrid IC that uses power MOSFETs in the output stage.
It includes a built-in microstepping controller and is based on a unipolar constant-current PWM system.
The STK672-040-E supports application simplification and standardization by providing a built-in 4 phase distribution stepping motor controller.
It supports five excitation methods: 2 phase, 1-2 phase, W1-2 phase, 2W1-2 phase, and 4W1-2 phase excitations, and can provide control of the basic stepping angle of the stepping motor divided into 1/16 step units.
It also allows the motor speed to be controlled with only a clock signal.
The use of this hybrid IC allows designers to implement systems that provide high motor torques, low vibration levels, low noise, fast response, and high-efficiency drive.
Applications • Facsimile stepping motor drive (send and receive) • Paper feed and optical system stepping motor drive in copiers • Laser printer drum drive • Printer carriage stepping motor drive • X-Y plotter pen drive • Other stepping motor applications Note*: Conditions: VCC1 = 24V, IOH = 1.
5A, 2W1-2 excitation mode.
