ON Semiconductor STK672-600 Stepper Motor Driver

The STK672-600 by ON Semiconductor is a highly-integrated, high-voltage, high-current stepper motor driver IC designed to deliver optimal performance and reliability for a wide range of motor driving applications. This IC is part of ON Semiconductor's esteemed line of motor driver solutions, offering precision and efficiency in controlling stepper motors.

The STK672-600 incorporates a unipolar constant-current chopper-type stepping motor driver, which is capable of driving a two-phase bipolar stepper motor. The device is designed to operate at voltages up to 44V and can provide an output current of up to 2.5A. This makes it suitable for a variety of demanding applications, including office automation machines, factory automation equipment, and other industrial machines where precise motor control is essential.

One of the key features of the STK672-600 is its built-in micro-stepping controller, which allows for smooth and accurate motor rotation with less noise and vibration. The micro-stepping function can be set to full-step, half-step, quarter-step, or eighth-step modes, providing flexibility in the resolution of motor movement and enabling fine positional control.

The device is also equipped with various protection features to ensure safe and reliable operation. These include thermal shutdown (TSD), over-current shutdown (ISD), and under-voltage lockout (UVLO). These protective measures help to prevent damage to the IC and the motor in case of abnormal operating conditions.

ON Semiconductor's STK672-600 comes in a compact, heat-dissipating ZIP package, which facilitates efficient thermal management and saves space on the PCB. The package design, combined with the high level of integration, reduces the need for external components, simplifying the circuit design and reducing overall system costs.

For designers and engineers looking for a robust and versatile stepper motor driver, the STK672-600 offers a perfect blend of performance, precision, and protection, making it an excellent choice for driving stepper motors in a variety of industrial and commercial applications.
