ON Semiconductor STK672-120-E Stepper Motor Driver

The STK672-120-E is a highly-integrated, high-efficiency stepper motor driver module designed by ON Semiconductor. This innovative component is engineered to drive a two-phase bipolar stepper motor in a variety of applications, ranging from office automation machines to factory automation and control systems.

The driver is built using a hybrid IC technology that combines bipolar and CMOS control circuitry with power FETs to provide a compact, high-performance solution. It is capable of operating at a wide range of power supply voltages from 10V to 42V, making it versatile for different power environments.

One of the key features of the STK672-120-E is its built-in micro-stepping controller, which allows for precise motor control. This feature enables smoother motion, increased step resolution, and improved positioning accuracy without the need for complex external circuitry or software. It supports various driving modes, including full-step, half-step, quarter-step, and eighth-step, providing flexibility to match the requirements of different applications.

The device also includes multiple built-in protection features to ensure reliable and safe operation. These protections include thermal shutdown, over-current, and under-voltage lockout, which safeguard the module and the motor from potential damage caused by abnormal operating conditions.

For ease of use, the STK672-120-E comes in a compact, multi-pin package that simplifies the PCB design process and reduces the overall footprint of the motor control section in the final application. This, combined with its high integration level, reduces the number of external components required, which in turn minimizes system costs and accelerates time to market.

Whether for driving the stepper motors in printers, scanners, vending machines, or robotic applications, the ON Semiconductor STK672-120-E stepper motor driver provides a reliable and efficient solution that engineers and designers can trust to deliver consistent performance and durability.
