Type
Function
Logic input
Step clock input. The state machine makes one step on each rising
edge.
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 must be connected to GND or +5 V.
Power supply
Bridge A source pin. This pin must be connected to power ground
through a sensing power resistor.
RC pin
RC network pin. A parallel RC network connected between this pin
and ground sets the current controller OFF time of bridge A.
Power output Bridge A output 1.
GND
Ground terminals. In PowerDIP24 and SO24 packages, these pins
are also used for heat dissipation towards the PCB. On PowerSO36
package the slug is connected to these pins.
Power output Bridge B output 1.
RC pin
RC network pin. A parallel RC network connected between this pin
and ground sets the current controller OFF time of bridge B.
