STK673-010-E:Bipoler 3-Phase Microstepping Motor Driver
The STK673-010-E is a 3-phase stepping motor driver hybrid IC with built-in microstep controller having a bipolar constant current PWM system, in which a power MOSFET is employed at an output stage.It includes a 3-phase distributed controller for a 3-phase stepping motor to realize a simple configuration of the motor driver circuit.The number of motor revolution can be controlled by the frequency of external clock input. 2, 2-3, W2-3 and 2W2-3-phase excitation modes are available. The basic step angle of the stepping motor can be separated as much as one-eighth 2-3-phase to 2W2-3-phase excitation mode control quasi-sine wave current, thereby realizing low vibration and low noise.And the STK673-010-E has heat sink installation holes, so it is easy to install a heat sink.
特性
- 4 types of modes, i.e. 2, 2-3, W2-3 and 2W2-3 phase excitations, are available which can be selected based on rising of clock signals
- Phase is maintained even when the excitation mode is changed
- An MOI output terminal which outputs 1 pulse per 1 cycle of phase current
- A built-in current detection resistor(0.227ohm)
