CLOCK
Logic Input
Step Clock input. The state machine makes one step on
each rising edge.
2
11
CW/CCW
Logic Input
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.
3
12
SENSEA
Power Supply
Bridge A Source Pin. This pin must be connected to Power
Ground through a sensing power resistor.
413
RCA
RC Pin
RC Network Pin. A parallel RC network connected
between this pin and ground sets the Current Controller
OFF-Time of the Bridge A.

OUT1A
Power Output
Bridge A Output 1.
6, 7,
18, 19
1, 18,
19, 36
GND
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.
8
22
OUT1B
Power Output
Bridge B Output 1.
924
RCB
RC Pin
RC Network Pin. A parallel RC network connected
between this pin and ground sets the Current Controller
OFF-Time of the Bridge B.
10
25
SENSEB
Power Supply
Bridge B Source Pin. This pin must be connected to Power
Ground through a sensing power resistor.
11
26
VREFB
Analog Input
Bridge B Current Controller Reference Voltage.
Do not leave this pin open or connected to GND.
12
27
HALF/FULL
Logic Input
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.
13
28
CONTROL
Logic Input
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.
14
29
EN
Logic Input (6)
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.
15
30
VBOOT
Supply
Voltage
Bootstrap Voltage needed for driving the upper Power
MOSFETs of both Bridge A and Bridge B.
16
32
OUT2B
Power Output
Bridge B Output 2.
17
33
VSB
Power Supply
Bridge B Power Supply Voltage. It must be connected to
the Supply Voltage together with pin VSA
20
4
VSA
Power Supply
Bridge A Power Supply Voltage. It must be connected to
the Supply Voltage together with pin VSB
