ON Semiconductor STK672-732AN-E Stepper Motor Driver

The STK672-732AN-E from ON Semiconductor is an advanced stepper motor driver that is designed to provide a flexible, high-performance solution for controlling 2-phase stepper motors. This integrated circuit is part of the well-regarded STK600 series and is known for its reliability and ease of use, making it an ideal choice for a wide range of applications, including office automation machines, factory automation systems, and consumer electronics.

This stepper motor driver incorporates a unipolar constant-current motor driver, which is capable of micro-stepping operation. The STK672-732AN-E supports various excitation modes, enabling precise control of motor speed and position. With the capability to drive motors with voltages up to 46V and currents up to 2A, this IC can handle a broad spectrum of stepper motors, from small to medium-sized types.

The device features a built-in non-volatile memory (NVM) to store configuration settings, which simplifies the design process and reduces the need for external components. The NVM also ensures that the motor driver retains its settings even after power cycles, providing consistent performance across uses.

One of the key benefits of the STK672-732AN-E is its thermal shutdown function, which protects the IC from overheating. This is particularly important in applications where the motor may be subject to continuous operation or high-load conditions. Additionally, the built-in overcurrent protection and under-voltage lockout features safeguard the motor and the driver from various electrical faults, enhancing the system's overall reliability.

With its compact design, the STK672-732AN-E comes in a multi-power package, which facilitates efficient heat dissipation and allows for a smaller PCB footprint. This makes the device particularly suitable for applications where space is at a premium.

Whether you are developing a new stepper motor control system or upgrading an existing one, the ON Semiconductor STK672-732AN-E offers a high-quality, robust solution that can meet the demands of a diverse range of motor control applications.
