Logic inputs
Pins CONTROL, HALF/FULL, CLOCK, RESET and CW/CCW are TTL/CMOS and µC
compatible logic inputs. The internal structure is shown in
on and turn-off thresholds are respectively V
Pin EN (Enable) has identical input structure with the exception that the drain of the
overcurrent and thermal protection MOSFET is also connected to this pin. Due to this
connection, some care must be taken in driving this pin. The EN input may be driven in one
of two configurations, as shown in
structure, a pull-up resistor R
If the driver is a standard push-pull structure, the resistor R
connected, as shown in
kΩ to 180 kΩ. Recommended values for R
More information on selecting the values is found in
