The STK672-040-E is a stepping motor driver Hybrid IC uses power MOSFETs in the output stage. It includes a built-in microstepping controller and is based on unipolar constant-current PWM system. It supports application simplification and standardization by providing a built-in 4-phase distribution stepping motor controller. It supports five excitation methods of 2-phase, 1 to 2 phase, 1W 2 phase, 2W 1 to 2 phase and 4W 1 to 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.
Phase retention even if excitation is switched
Excitation phase state can be verified in real time using the MO1, MO2 and MOI signal output pins
External excitation PWM drive allows a wide operating supply voltage range to be used
Current detection resistor (0.33R) built-in the hybrid IC itself
