2-Phase Unipolar Stepper Motor Driver
SLA707xM Series
February, 2006
■General Description
■Package—SLA23Pin
Combining low-power CMOS logic with high-current, high-voltage
power FET outputs, the Series SLA707xM translator/drivers provide
complete control and drive for a two-phase unipolar stepper motor
with internal fixed off time and pulse-width modulation (PWM)
control of the output current in a power multi-chip module
(PMCM™).
There are no phase-sequence tables, high-frequency control lines, or
complex interfaces to program. The CMOS logic section provides the
sequencing logic, direction, control, synchronous/asynchronous PWM
operation, and a "sleep" function. The minimum CLOCK input is an
ideal fit for applications where a complex µP is unavailable or
overburdened. TTL or LSTTL may require the use of appropriate
pull-up resistors to ensure a proper input-logic high. For PWM current
control, the maximum output current is determined by the user's
selection of a reference voltage and sensing resistor. The NMOS
outputs are capable of sinking up to 1, 1.5, 2, or 3 A (depending on
device) and withstanding 46 V in the off state.
Clamp diodes provide protection against inductive transients. Special
power-up sequencing is not required.
Full-,and Half-step operation are externally selectable for the
SLA7070/71/72/73MR. Full-, Half-, quarter-, and eighth-, and
sixteenth-step operation are externally selectable for the
SLA7075/76/77/78MR.
Half-step excitation alternates between the one-phase and two-phase
modes (A-AB-B-AB-A-AB-BAB),providing an eight-step sequence.

• Take precautions to avoid noise on the VDD line:
Switching noise from PCB traces, where high current flows, to the VDD line should be minimized
because the noise level more than 0.5V on the VDD line may cause malfunctioning operation.
The tip for avoiding such problem is to separate the logic GND (S-GND) and the power GND (P-GND) on
the PCB, and then connect them together at IC GND pin (pin 12).

Cautions and warnings
The calculation of control current
SLA707xMR control current Io (at Mode F) is calculated as follows:
VREF
IO =
RS
Setting the REF voltage more than 2V activates the sleep mode 1 (all outputs are in OFF state).
Even in this case, the internal logic circuit is alive.
Logic input/output (RESET, CLOCK, CW/CCW, M1, M2, M3, SYNC, Mo)
• The timing shown below shall comply with the "Logic input timing".
-The rising edge timing of CW/CCW, M1, M2, M3 and CLOCK input
-The RESET release timing (=the falling edge on RESET input) and the rising edge timing of CLOCK
input
*In case the above does not comply with the "Logic input timing", the device may operate with an
unexpected sequence.
• Be sure not to leave the logic inputs (RESET, CLOCK, CW/CCW, M1, M2, M3, SYNC) open.
Be sure to connect the unused logic inputs to VDD or GND.
*In case any of the logic inputs are left "OPEN", malfunction may occur due to external noises.
• When the logic output (Mo) is not used, be sure to keep it "OPEN".
*In case it is connected to VDD or GND, it may cause the device's deterioration or/and breakdown.

Notice
This device has C-MOS inputs. Please note the following contents.
• When a static electricity is liable to be troublesome, especially in winter, be sure to control the
room humidity properly.
• Be sure to take some proper measures for wirings from the IC input pins and for assembly
processes in order not to apply static charges to IC leads. PC board pins should be shorted together
to keep them in the same potential to avoid this kind of trouble.
