STK672-410 General Description

The STK672-410 is a versatile and reliable hybrid stepping motor driver module that is perfect for a variety of stepper motor applications. With its integrated power MOSFET H-bridge configuration, it is capable of delivering up to 2.5A of current per phase, ensuring smooth and efficient motor control. The built-in thermal shutdown and overcurrent protection features make it a safe and dependable choice for any project

Key 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.

Application

Office photocopiers, printers, etc.
