Combining low-power
CMOS logic with high-current and high-
voltage bipolar outputs, the UCN5804B and UCN5804LB BiMOS II translator/ drivers provide complete control and drive for a four-phase unipolar steppermotor with continuous output current ratings to 1.
25 A per phase (1.
5 A startup) and 35 V.
The
CMOS logic section provides the sequencing logic, DIRECTION and OUTPUT ENABLE control, and a power-on reset function.
Three stepper-motor drive formats, wave-drive (o...
