STK672-410 Description
ENA0752 STK672-410 Thick-Film Hybrid IC 2-phase Stepping Motor Driver http://onsemi. Overview The STK672-410 is a hybrid IC for use as a unipolar, 2-phase stepping motor driver with PWM current control. Applications Office photocopiers, printers, etc.
STK672-410 Key Features
- Entry of external clock is enough to activate the micro step sinusoidal driver
- The 4-phase distributor switching timing can be set to occur either on both rising and falling edge detection or on
- A phase holding function is provided to prevent phase skip during switching of excitation in the course of operation
- The motor current is set by a voltage divider formed by an external resistor connected to the Vref pin
- The CLK input pin is provided with an internal noise filtering circuit in addition to a Schmidt circuit to increase the
- When set low, the ENABLE pin turns off the motor drive current for all phases and retains the phase excitation state
