LOGIC INPUTS
Pins CONTROL, HALF/FULL, CLOCK, RESET and CW/CCW are TTL/CMOS and uC compatible logic inputs.
The internal structure is shown in Fig. 7. Typical value for turn-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 needs to be taken in driving
this pin. The EN input may be driven in one of two configurations as shown in Fig. 8 or 9. If driven by an open
drain (collector) structure, a pull-up resistor R
driver is a standard Push-Pull structure the resistor R
