Description
Direction command input for determining motor turning direction
Motor steeping pulse input, phase logic operation triggered by negative edge of
STEP signal
Half/Full step mode switching input
H level in full step mode and L level in half step mode
Phase logic initial input
Phase output initial status detection output
A value of connected capacitor determines lock detection time (Ton) and auto
resume time (Toff)
SGND (Logic GND) and PGND (Analog GND) is not connect in the IC
SGND and PGND pins should be connected ground respectively.
Auto Current Down output terminal
L level in active
Step sequence output terminals
P1/DIS1(P2/DIS2) determine a sequence output on Phase1(2) for driver IC
P1(P2) determine a motor current direction on Phase1(2) for driver IC
DIS1(DIS2) determine a phase current OFF mode at the half-step
Logic power supply voltage terminal
