Product Summary
The STK672-010M is a 4-phase stepping motor driver IC that adopts power MOSFET for its output stage and that uses a unipolar fixed-current chopper scheme. Since the STK672-010M includes a built-in 4-phase distribution controller, the stepping motor driver circuit and the control scheme can be simplified, and the stepping motor driver circuit structure can be standardized. The STK672-010M provides high torque, low vibration, and rapid response based on a W1-2 phase excitation drive scheme. The motor current is voluntary set from externals. Since, compared to the earlier STK672-010M. It has a smaller package size and reduced drive power disspation. It provides a wider operating power supply voltage range.
Parametrics
STK672-010M maximum ratings: (1)Vcc max when the condition is no signal: 52 V; (2)IOH when the condition is 0.5s and 1 pulse: 2.5A; (3)Ear max: 38mJ; (4)VIN max: 7.0V; (5)Tc max: 1.5℃; (6)Tj max: 150℃; (7)Tstg: -40 to +125℃.
Features
STK672-010M features: (1)The STK672-010M can easily implement stepping motor drive applications with the procision of a DC power supply and a clock pulse oscillator; (2)The STK672-010M supports 4 excitation types selected by the excitation mode setting; (3)Schmitt input pins; (4)Controller inputs are CMOS compatible, thus allowing direct control from I/O ports or special-purpose controller LSIs; (5)An interval is set up during mutual switching of the AA and BB phase output signals in 4-phase 2 excitation mode.
