Thick-Film Hybrid IC

Unipolar Fixed-Current Chopper (Self-Excited PWM)

Scheme and Built-in Phase Signal Distribution IC

STK672-120-E

Two-Phase Stepping Motor Driver

(Square Wave Drive) Output Current 2.4A

Overview

The STK672-120-E is a unipolar fixed-current chopper type 2-phase stepping motor driver hybrid IC. It features power

MOSFETs in the output stage and a built-in phase signal distribution IC. The incorporation of a phase distribution IC

allows the STK672-120-E to control the speed of the motor based on the frequency of an external input clock signal.

It supports two types of excitation for motor control: 2-phase excitation and 1-2 phase excitation. It also provides a function

for switching the motor direction.

Applications

• Two-phase stepping motor drive in send/receive facsimile units

• Paper feed in copiers, industrial robots, and other applications that require 2-phase stepping motor drive

Features

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

• The excitation type is switched according to the state (low or high) of the MODE pin. The mode is set to 2-phase or 1-2

phase excitation on the rising edge of the clock signal.

• A motor direction switching pin (the CWB pin) is provided.

• All inputs are schmitt inputs and 40kΩ (typical: –50 to +100%) pull-up resistors are built in.

• The motor current can be set by changing the Vref pin voltage. Since a 0.165Ω current detection resistor is built in, a

current of 1A is set for each 0.165V of applied voltage.

• The input frequency range for the clock signal used for motor speed control is 0 to 25kHz.

• Supply voltage ranges: V

= 10 to 42V, V = 5.0V ±5%

• This IC supports motor operating currents of up to 2.4A at Tc = 105°C, and of up to 4.0A at Tc = 25°C.
