STK672-080-E Descrizione generale

The compact package of the STK672-080-E, coupled with its high level of reliability, makes it an excellent choice for demanding applications in industries where precision and performance are critical. Whether it's in industrial automation or automotive systems, this hybrid stepping motor driver IC delivers consistent and efficient motor control, enhancing the overall functionality and productivity of the equipment

Caratteristiche principali

Can implement stepping motor drive systems simply by providing a DC power supply and a clock pulse generator.
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
Phase retention even if excitation is switched.
Provides the MOI phase origin monitor pin.
The CLK input counter block can be selected to be one ofthe following by the high/low setting of the M3 input pin.
1) Rising edge only
2) Both rising and falling edges
The CLK input pin includes 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.
External excitation PWM drive allows a wide operating supply voltage range (VCC1 = 10 to 45V) to be used.
Current detection resistor (0.15Ω) built-in the hybrid IC itself.
Power MOSFETs adopted for low drive loss.
Provides a motor output drive current of IOH= 2.8A. (at Tc = 105°C)
