The UCN5804B is a stepper-motor translator/driver. Combining low-power CMOS logic with high-current and high-voltage bipolar outputs, the UCN5804B provides complete control and drive for a four-phase unipolar stepper-motor with continuous output current ratings to 1.25 A per phase (1.5 A startup) and 35 V. The bipolar outputs are capable of sinking up to 1.5 A and withstanding 50 V in the off state (sustaining voltages up to 35V). It is rated for operation over the temperature range of -20℃ to +85℃. The UCN5804B is supplied in a 16-pin dual in-line plastic batwing package with a copper lead frame and heat-sinkable tabs for improved power dissipation capabilities.
