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 stepper-
motor 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 half-
step 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.

Note that the UCN5804B (dual in-line package)
and UCN5804LB (small outline IC package) are
electrically identical and share a common
terminal number assignment.
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 exces-
sive.
Both devices are rated for operation over the temperature range of -20°C
to +85°C. 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; the UCN5804LB is supplied in a 16-lead plastic
SOIC batwing package with a copper lead frame and heat-sinkable tabs.

APPLICATIONS INFORMATION
Half Step = L, One Phase = H
Internal power-on reset (POR) circuitry resets
OUTPUTA (and OUTPUTD in the two-phase
drive format) to the on state with initial applica-
tion 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 se-
quence 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.
ON
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 approxi-
mately 145°C.
