STK672-060
Continued from preceding page.
• To match the motor characteristics, the vector locus
during microstepping drive can be selected to be any one
of four modes: circular mode, one inside mode, and two
outside modes.
• The phase is retained if excitation is switched during
operation.
• The excitation phase state can be verified in real time
using the MO1, MO2, and MOI signal output pins.
• The clock input counter block supports two signalsense
modes selected by the high or low state of the M3 pin.
—Rising edges only
—Both rising and falling edges
• The CLK and RETURN input pins have built-in circuits
that prevent malfunctions due to external noise pulses.
• Both an ENABLE and a RESET pin are provided as
Schmitt trigger inputs with built-in 20 kΩ (typical) pull-
up resistors.
• No audible noise is generated by the differences in the
time constant between phases A and B when the motor
position is held fixed due to the adoption of external
excitation.
• The reference voltage Vref can be set to any level
between 0 and 1/2 VCC2. This allows the STK672-060
to provide microstepping operation even for small motor
currents.
<Drive Block>
• Provides a wide range of operating supply voltage
required for external excitation PWM drive (VCC1 = 10
to 45 V).
• Current detection resistor (0.22 Ω) built-in the hybrid IC
itself.
• Power MOSFETs adopted for low drive loss.
• Provides a motor output drive current of IOH = 1.2 A.
