STK672-400C-E

Overview

The STK672-400C-E is a hybrid IC for use as a unipolar, 2-phase stepping motor driver with PWM current control.

Applications

• Office photocopiers, printers, etc.

Features

• Entry of external clock is enough to activate the micro step sinusoidal driver.

• The excitation mode of 2, 1-2, W1-2, 2W1-2, or 4W1-2 can be selected with the external pin.

• The 4-phase distributor switching timing can be set to occur either on both rising and falling edge detection or on

rising edge detection only with an external pin (MODE3).

• 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

margin for extraneous noise.

• When set low, the ENABLE pin turns off the motor drive current for all phases and retains the phase excitation state.
