STK672-040
Continued from preceding page.
• 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 20 kΩ (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 0 V and 1/2VCC2.
<Driver Block>
• External excitation PWM drive allows a wide operating
supply voltage range (VCC1 = 10 to 45 V) to be used.
• Current detection resistor (0.33 Ω) built into the hybrid
IC.
• Power MOSFETs for minimal driver loss
• Motor output drive currents IOH up to 1.5 A.
