The STK672-040-E from On Semiconductor is a thick-film hybrid IC designed for unipolar stepping motor drive applications. It features a built-in microstepping controller and uses a constant-current PWM system with power MOSFETs in the output stage.
This IC supports five excitation methods (2 phase, 1-2 phase, W1-2 phase, 2W1-2 phase, and 4W1-2 phase) and allows for control of stepping angles divided into 1/16 step units. Motor speed can be controlled using only a clock signal. Key electrical specifications include an output current of 1.5A and an operating voltage range of 10V to 45V.
The STK672-040-E is housed in a 22-SIP package and is designed for through-hole mounting. Its features enable systems with high motor torques, low vibration, low noise, fast response, and high efficiency.
Applications include stepping motor drive for facsimiles, copiers, laser printers, and X-Y plotters.
