STEPPER MOTOR DRIVER VID66-06
GENERAL DESCRIPTION
The quad stepping motor driver VID66-06 is a monolithic CMOS device intended to be
used as an interface circuit to ease the use of the stepper motor VID29-XX. It is
specifically designed for applications in the car dashboard. The chip allows the user to
drive four motors as it contains four identical drivers on the same chip.
The driver circuit converts a pulse train f(scx) into a current level sequence sent to the
motor coils. This sequence is used to produce the micro stepping movement of the
motor. Each inner driver in the chip generates 2 sequent logic pulse signals and
provides shaft stepping angle resolution 1/12°.

FEATURES
¾ Generates micro steps
¾ Glitch filters on all inputs
¾ VDD = 4.5 to 5.5V
¾ Low EMI emission

HANDING PROCEDURES
Stresses beyond these listed maximum ratings may cause permanent damage to the
device. Exposure to conditions beyond specified operating conditions may affect
device reliability or cause malfunction.
The device has built-in protection against high static voltages or electric fields; however,
anti-static precautions must be taken as for any other CMOS component. Unless
otherwise specified, proper operation can only occur when all terminal voltages are
kept within the supply voltage range. Unused inputs must always be tied to a defined
logic voltage level unless otherwise specified.

CIRCUIT PROTECTIONS
To filter fast voltage transients, it is highly recommended to connect two 100nF ceramic
capacitors to the power supply pins, one on either side and as close as possible to the
chip.
Moreover, to protect the chip against latch-up, a 5uF capacitor per motor connected
should be added. Thus, for 4 motors, typically a 22uF capacitor must be used, either
electrolytic or tantalum. Note this capacitor can be placed close to the voltage
regulator.

RECOMMENDED POWER UP
In order to power up the circuit in a defined manner, it is recommended to keep the
RESET input low while the VDD voltage is raising. After a delay of about 1ms, the
RESET can be released (i.e. set high). Depending on the micro controller used, an
external pull-down resistor might be required to properly set the RESET state at low
during the start-up.

FUNCTIONAL DESCRIPTION
The rising edge of the f(scx) input signal moves the rotor by one micro step.
The input signal "CW/CCW" (clockwise / counterclockwise) controls the direction of
rotation of the motor.

INPUT GLITCH FILTER & LEVEL SHIFTER
All logic inputs of this driver are armed with a glitch filter to avoid erroneous information
due to spikes and glitches on the input signal lines. All negative or positive pulses of
less than 20 ns width are ignored.
A minimum signal pulse width (positive or negative) of 450 ns guarantees correct
function over the full temperature range.
All logic inputs also feature a level shifter, which allows for operation of the circuit at a
higher supply voltage (VDD) than the circuits driving the inputs. This is in order to drive
the VID motors at a higher torque level.
