Product Overview

The STK672-440BN-E is a Hybrid IC for use unipolar, 2-phase stepper motor driver with PWM current control. 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 stepper 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 stepper 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. In addition the STK672-440BN-E has various protective functions against overcurrent, overheat and motor terminal open.
  • Built-in power on reset function
  • Micro-step sine wave-driven driver can be activated merely by inputting an external clock
  • Phase is maintained even when the excitation mode is changed
  • Rotational direction switching function
  • Supports Schmitt input for 2.5V high level input
  • ENABLE pin can be used to cut output current while maintaining the excitation mode
  • With a wide current setting range, power consumption can be reduced during standby
  • No motor sound is generated during hold mode due to external excitation current control
  • Supports compatible pins with STK672-432BN/-442BN-E
  • Built-in micro stepping controller
  • Built-in current detection resistor
  • Superior in safety drive
  • Easy to design and reduce the mounting area
