STK672-080 Stepping Motor Driver (Sine Wave Drive) Output Current : 2.8 A (No Heat Sink)

External Excitation Chopper Drive Block Description VCC1 IOFF ION Enable ØA (control signal) Current divider Vref A=1 L2 L1 Divider CR oscillator 800kHz 45kHz S – + D1 MOSFET AND Q Latch circuit R Noise filter Rs A13263 Driver Block Basic Circuit Structure Since this hybrid IC adopts an external excitation method, no external oscillator circuit is.

Features

a significantly smaller package for easier mounting in end products.
• One of five drive types can be selected with the drive mode settings (M1, M2, and M3) —2 phase excitation drive —1-2 phase excitation drive —W1-2 phase excitation drive —2W1-2 phase excitation drive —4W1-2 phase excitation drive
• Phase retention even if excitation is switched.
• The MOI phase origin monitor pin is provided.
• The CLK input counter block can be selected to be one of the following by the high/low setting of the M3 input pin. —Rising edge only —Both rising and falling edges Note
