OUTPUT D GROUND bining low-power CMOS logic with high-current and high-voltage bipolar outputs, the UCN5804B and UCN5804LB BiMOS II translator/ drivers provide plete 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...
