2 / 19 page STK672-050-E No.5228-2/19 Features • Can implement stepping motor drive systems simply by providing a DC power supply and a clock pulse generator. <Control Block Features> • One of five drive types can be selected with the drive mode settings (M1, M2, and M3) 1) 2 phase excitation drive 2) 1-2 phase excitation drive 3) W1-2 phase excitation drive 4) 2W1-2 phase excitation drive 5) 4W1-2 phase excitation drive • Provides four freely selectable modes for the vector locus during microstepping drive: circular mode, one inside mode, and two outside modes. • Phase retention even if excitation is switched. • The excitation phase state can be verified in real time using the MO1, MO2, and MOI signal output pins. • The CLK input counter block can be selected to be one of the following by the high/low setting of the M3 input pin. 1) Rising edge only 2) Both rising and falling edges • The CLK and RETURN input pins include built-in malfunction prevention circuits for external pulse noise. • ENABLE and RESET pins provided. These are Schmitt trigger inputs with built-in 20kΩ (typical) pull-up resistors. • No noise generation due to the difference between the A and B phase time constants during motor hold since external excitation is used. • Microstepping operation supported even for small motor currents, since the reference voltage Vref can be set to any value between 0V and 1/2VCC2. <Driver Block> • External excitation PWM drive allows a wide operating supply voltage range (VCC1 = 10 to 45V) to be used. • Current detection resistor (0.2Ω) built-in the hybrid IC itself. • Power MOSFETs adopted for low drive loss. • Provides a motor output drive current of IOH = 3.0A.
