STK672-440BN-E Description

Short technical summary and product information.

The STK672-440BN-E is a fully integrated motor driver from On Semiconductor that combines control and power stage circuitry in a 19-SSIP formed-lead package. It is designed for unipolar stepper motors and uses power MOSFET outputs arranged as two half bridges. The device supports parallel interface control and step resolutions of 1, 1/2, 1/4, 1/8, and 1/16.

 

The driver operates over a voltage range of 0V to 46V and can deliver up to 3A of output current. Its case temperature operating range is 0°C to 105°C, making it suitable for a variety of electromechanical positioning and motion control applications. The through-hole mounting style simplifies assembly in traditional PCB designs.

 

With an integrated power stage, the STK672-440BN-E minimizes external components in unipolar stepper motor drive circuits. The parallel interface allows straightforward connection to MCUs or digital control logic. This motor driver is placed under the Integrated Circuits > Power Management (PMIC) > Motor Drivers and Controllers category.
