BiMOS II UNIPOLAR
STEPPER-MOTOR TRANSLATOR/DRIVER
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 (one-phase), two-phase, and half­step are externally selectable. The inputs are compatible with standard CMOS, PMOS, and NMOS circuits. TTL or LSTTL may require the use of appropriate pull-up resistors to ensure a proper input-logic high.
The wave-drive format consists of energizing one motor phase at a time in an A-B-C-D (or D-C-B-A) sequence. This excitation mode consumes the least power and assures positional accuracy regardless of any winding inbalance in the motor. Two-phase drive energizes two adjacent phases in each detent position (AB-BC-CD-DA). This sequence mode offers an improved torque-speed product, greater detent torque, and is less susceptible to motor resonance. Half-step excitation alternates between the one-phase and two-phase modes (A-AB-B-BC-C-CD-D-DA), providing an eight-step sequence.
The bipolar outputs are capable of sinking up to 1.5 A and withstanding 50 V in the off state (sustaining voltages up to 35 V). Ground-clamp and flyback diodes provide protection against inductive transients. Thermal protection circuitry disables the outputs when the chip temperature is exces­sive.

APPLICATIONS INFORMATION
Internal power-on reset (POR) circuitry resets OUTPUTA (and OUTPUTD in the two-phase drive format) to the on state with initial applica­tion of the logic supply voltage. After reset, the circuit then steps according to the tables.
The outputs will advance one sequence position on the high-to-low transition of the STEP INPUT pulse. Logic levels on the HALF-STEP and ONE-PHASE inputs will determine the drive format (one-phase, two-phase, or half-step). The DIRECTION pin determines the rotation se­quence of the outputs. Note that the STEP INPUT must be in the low state when changing the state of ONE-PHASE, HALF-STEP, or DIRECTION to prevent erroneous stepping.
All outputs are disabled (off) when OUTPUT ENABLE is at a logic high. If the function is not required, OUTPUT ENABLE should be tied low. In that condition, all outputs depend only on the state of the step logic.

During normal commutation of a unipolar stepper motor, mutual coupling between the motor windings can force the outputs of the UCN5804B below ground. This condition will cause forward biasing of the collector-to-substrate junction and source current from the output. For many L/R applications, this substrate current is high enough to adversely affect the logic circuitry and cause misstepping. External series diodes (Schottky are recommended for increased efficiency at low-voltage operation) will prevent substrate current from being sourced through the outputs. Alternatively, external ground clamp diodes will provide a preferred current path from ground when the outputs are pulled below ground.
Internal thermal protection circuitry disables all outputs when the junction temperature reaches approximately 165°C. The outputs are enabled again when the junction cools down to approxi­mately 145°C.
