STK673-011-E

Overview

The STK673-011-E is a thick-film hybrid integrated circuit designed as a three-phase stepping motor driver. It features a built-in microstep controller utilizing a bipolar constant current PWM system with power MOSFETs at the output stage. The device supports a supply voltage range of 16 V to 30 V and delivers a maximum IGBT collector current of 2.4 A, with a maximum collector-emitter voltage of 30 V. Housed in a 25-pin SIP package for through-hole mounting, it measures 64 mm in length, 8.5 mm in width, and 32 mm in height. The component operates reliably up to a maximum temperature of +150 °C.

Feature Summary

Integrates a microstep controller with a bipolar constant current PWM system
Employs power MOSFETs at the output stage for efficient driving
Designed specifically for three-phase stepping motor applications

Applications

Three-phase stepping motor control systems
Precision positioning mechanisms requiring microstepping
