STK673-010 3-Phase Stepping Motor Driver (sine wave drive) Output Current 2.4A
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. 2-3, W2-3 and 2W23-phase excitation modes are available. The basic step angle of the stepping motor can be separated as much as one-eighth to 2W2-3-phase excitation mode control quasi-sine wave current, thereby realizing low vibration and low noise.Applications
a 3-phase stepping motor driver for transmission and reception in a facsimile. a 3-phase stepping motor driver for feeding paper feed or for an optical system in a copying machine. Industrial machines or products employing 3-phase stepping motor driving.
An MOI output terminal which outputs 1 pulse per 1 cycle of phase current. A CW/CCW terminal which switches the rotational direction. A Hold terminal which temporarily holds the motor in a state where the phase current is conducted. An Enable terminal which can forcibly turns OFF a MOSFET a 6 output driving element in normal operation Schmitt inputs with built-in pull-up resistor (20 k typ) Motor current can be set by changing the voltage of the Vref terminal (0.63V per 1A, dealing as much 1/2VCC2 (4A)). The clock input for controlling the number of motor revolution lies in a range to 50kHz. Supply voltage: 5.0V±5% A built-in current detection resistor (0.227) A motor current during revolution can deal with as high = 105°C and as high 50°C or lower.Features
Number of motor revolution can be controlled by the frequency of external clock input. 4 types of modes, i.e., 2-3, W2-3 and 2W2-3-phase excitations, are available which can be selected based on rising of clock signals, by switching Highs and Lows of Mode A and Mode B terminals. Setting a Mode C terminal Low allows an excitation mode that is based on rising and falling of a clock signal. By setting the Mode C terminal Low, phases that are set only by Mode A and Mode B can be changed to other phases as follows without changing the number of motor revolution: 2-phase may be switched 2-3phase; 2-3-phase may be switched to W2-3-phase; and W2-3-phase may be switched to 2W2-3-phase. Phase is maintained even when the excitation mode is changedSANYO Electric Co., Ltd. Semiconductor Business Headquarters
