STK672-532

Overview

The STK672-532 is a hybrid IC for use as a unipolar, 2-phase stepping motor driver with PWM current control.

Applications

• Office photocopiers, printers, etc.

Features

• The motor speed can be controlled by the frequency of an external clock signal.

• 2-phase excitation or 1-2 phase excitation is selected according to switching the state of the MODE pin (low or high).

• The phase is maintained even if the excitation mode is switched in the middle of operation.

• The direction of rotation can be changed by applying a high or low signal to the CWB pin used to select the direction

of rotation.

• Supports schmitt input for 2.5V high level input.

• Incorporating a current detection resistor (0.165Ω: resistor tolerance ±2%), motor current can be set using two

external resistors.

• Equipped with an ENABLE pin that, during clock input, allows motor output to be cut-off and resumed later while

maintaining the same excitation timing.
