STK673-011-E, 3-Phase Stepping Motor Driver

Ordering number : ENA1137B STK673-011-E Thick-Film Hybrid IC 3-Phase Stepping Motor Driver http://onsemi.com Overview The STK673-011-E is a 3-phase stepping motor driver hybrid IC with built-in microstep controller having a bipolar constant current PWM system, in which a power MOSFET is employed at an output stage.

It includes a 3-phase distributed controller for a 3-phase stepping motor to realize a simple configuration of the motor driver circuit.

The number of motor revolution can be contr

STK673-011-E Features

* Number of motor revolution can be controlled by the frequency of external clock input.

* 4 types of modes, i.e., 2, 2-3, W2-3 and 2W2-3-phase excitations, are available which can be selected based on rising of clock signals, by switching highs and lows of Mode A and Mode B terminal
