power MOSFETs in the output stage and a built-in phase signal distribution IC. The incorporation of a phase distribution IC allows the STK672-330 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. The STK672-330 features an ENABLE pin, a function not provided in the STK672-110. When the ENABLE p.

Chopper (External-Excited PWM) Scheme and Built-in Phase Signal Distribution IC Two-Phase Stepping Motor Driver (Square Wave Drive) Output Current: 1.8 A Overview The STK672-330 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 STK672-330 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
