Step Clock input. The state machine makes one step on
each rising edge.
Selects the direction of the rotation. HIGH logic level sets
clockwise direction, whereas LOW logic level sets
counterclockwise direction.
If not used, it has to be connected to GND or +5V.
Bridge A Source Pin. This pin must be connected to Power
Ground through a sensing power resistor.
RC Network Pin. A parallel RC network connected
between this pin and ground sets the Current Controller
OFF-Time of the Bridge A.
Bridge A Output 1.
Ground terminals. In PowerDIP24 and SO24 packages,
these pins are also used for heat dissipation toward the
PCB. On PowerSO36 package the slug is connected to
these pins.
Bridge B Output 1.
RC Network Pin. A parallel RC network connected
between this pin and ground sets the Current Controller
OFF-Time of the Bridge B.
Bridge B Source Pin. This pin must be connected to Power
Ground through a sensing power resistor.
Bridge B Current Controller Reference Voltage.
Do not leave this pin open or connected to GND.
Step Mode Selector. HIGH logic level sets HALF STEP
Mode, LOW logic level sets FULL STEP Mode.
If not used, it has to be connected to GND or +5V.
Decay Mode Selector. HIGH logic level sets SLOW DECAY
Mode. LOW logic level sets FAST DECAY Mode.
If not used, it has to be connected to GND or +5V.
Chip Enable. LOW logic level switches OFF all Power
MOSFETs of both Bridge A and Bridge B. This pin is also
connected to the collector of the Overcurrent and Thermal
Protection to implement over current protection.
If not used, it has to be connected to +5V through a
resistor.
Bootstrap Voltage needed for driving the upper Power
MOSFETs of both Bridge A and Bridge B.
Bridge B Output 2.
Bridge B Power Supply Voltage. It must be connected to
the Supply Voltage together with pin VS
Bridge A Power Supply Voltage. It must be connected to
the Supply Voltage together with pin VS
